How to calculate what days you can get pregnant. What days can you get pregnant? How to calculate them. Signs of successful conception after ovulation

You are planning a long-awaited baby and want to effectively calculate the day of conception or use a calendar method of contraception. In both cases, it is important to know your own cyclical features and periods when the likelihood of becoming pregnant is especially high. What proven methods exist for this, you will find out in the article.

Features of the woman's menstrual cycle

By nature itself, the female body has the ability to produce sex cells, and after their fertilization, to bear and give birth to a new little man. In scientific terms, the menstrual cycle (from the Latin menstruus - "lunar cycle") - periodic changes in the body of a healthy woman of reproductive age, making it possible to conceive a child. The duration of the cycle is purely individual, averaging 28 days (lunar month) ± 7 days.

Regular cycles are an indicator of a woman's health. Every time the female body thus prepares for pregnancy. The menstrual cycle is usually divided into the following phases:

A woman's menstrual cycle has three phases.

It is interesting! Did you know that the egg, being the largest cell in the human body, is about 600 times larger than the sperm, the smallest? A unique symbiosis of cells of maximum and minimum size born in 9 months!

So, regular menstruation and ovulation are an indicator of a woman's reproductive health. However, there are variants of the norm that everyone can face. We are talking about anovulation, or the absence of ovulation at certain periods of life. Such a menstrual cycle is characterized by the absence of ovulation and the luteal phase. Anovulation can occur against the background of stress and serious energy losses, and is also often observed in adolescents and women in a state of premenopause. Chronic absence of ovulation occurs in 15% of women, even against the background of hormonal balance. This dysfunction of the reproductive system requires a visit to a gynecologist, but is not always a cause for concern: during the year, each woman may have several cycles of anovulatory.

When is the most likely time to get pregnant?

There are many myths about favorable periods for conception. The most common:

1. You can not get pregnant before menstruation.
2. Sex during your period is safe.
3. In the days immediately following the menstruation, conception is impossible.

It is impossible to count on a 100% guarantee of these statements, you need to understand the features of the cycle. Following this infographic, you are least likely to conceive at the very end of your cycle.
Which days of the cycle are the most favorable for conception, and which are the least?

What is the situation in reality and what options may be - we understand together.

Is it possible to get pregnant before menstruation?

The calendar method of contraception is the safest for a woman's body, but does not give guarantees. Sometimes girls who regularly monitor their cycle and are absolutely sure that it is impossible to get pregnant before menstruation find two strips on the test. Doctors do not give a specific answer, how high is the likelihood of pregnancy in last days cycle. This does not happen often, but it is quite possible under certain conditions.

The less time has passed between unprotected sexual intercourse and the onset of menstruation, the more the chance of conception decreases. At the same time, in exceptional cases, successful fertilization of the egg occurred a few days before the start of a new cycle. The explanation for this is physiological features organism. The main factors causing the failure of the reproductive system:

• diseases of a viral and infectious nature;
• inflammatory processes;
• hormonal changes;
• difficult climatic conditions or a sharp change in climatic zones;
• stress.

These factors can delay the maturation of the egg for a sufficiently long period or prevent it altogether. In such a situation, a woman will not be able to correctly calculate the day of ovulation. There are several reasons that affect the fact that conception can occur a few days before the onset of menstruation:

1. Menses delay. For girls who are accustomed to irregular periods, delayed ovulation is also quite common. In this case, ovulation can begin both earlier and later than the middle of the menstrual cycle, so the possibility of becoming pregnant increases.
2. Maturation of several eggs at the same time. Similar malfunctions in the functioning of the ovaries can happen to any woman. This is not a pathology, but it can lead to conception before menstruation. With double ovulation, two eggs mature at once: the first, as expected, in the middle of the cycle, and the second - in the subsequent time.
3. Reception of hormonal OK. Oral contraceptives containing hormones (HOCs) reduce the formation of eggs in the ovaries, thereby changing the intensity and abundance of menstrual bleeding. If you stop taking HOC, a hormonal storm begins in the body, and more than 2 eggs can mature at the same time. Therefore, after a course of contraceptives, this probability increases dramatically.

The phenomenon of double ovulation is more typical for the fair sex, who do not have regular sexual intercourse, as their body tries to improve the chances of pregnancy. When a second ovulation occurs in a cycle, when hormone production is already decreasing, and the endometrial covers are preparing to peel off, even if the egg is fertilized and implanted, it is likely to be rejected. In such rare cases, the pregnancy is unlikely to last, the zygote (fertilized germ cell) will leave the uterus along with bleeding.

Another important factor is a constant sexual partner. If a woman has one partner for a long time, then the chances of conceiving grow at any time, including before the start of menstruation. This is possible because sperm, having entered the female body for the first time, is perceived by the immune system as an enemy object. Defender cells successfully attack spermatozoa, many die immediately. However, when the partner is permanent, the woman's immunity ceases to perceive his sperm as a foreign body. Spermatozoa can stay active for up to a week in a woman's genitals, thus regular intimate relationship with one partner increase.

Possibility of pregnancy during menstruation

Many girls are convinced that the period of menstruation is a 100% guarantee of safe sex. Indeed, the possibility of getting pregnant is extremely small, but it cannot be completely ruled out.

Indeed, in the first days of menstruation, when the upper layer of the uterine mucosa is rejected and the production of progesterone decreases, it is impossible to get pregnant. The new egg has not yet matured, and in conditions of bleeding, sperm cannot penetrate the uterine tubes. But by the end of the bleeding period, the opportunity to conceive increases, especially with prolonged bleeding or cycle failure.

Factors that increase the likelihood of getting pregnant are similar to the above:

1. double ovulation.
2. irregular cycle.
3. Lack of a permanent partner.
4. Short menstrual cycle.
5. Sperm activity up to 7 days after intercourse.
6. Violation of the rules for taking oral contraceptives (missing a pill, a combination of OK with antibiotics, self-administration of contraception).

Is it possible to get pregnant immediately after menstruation

It is impossible to answer this question with a categorical “no”, since there is still some chance of getting pregnant after the end of menstruation, which is associated with already familiar reasons:

• short menstrual cycle (21 days) - ovulation is likely in the coming days after the end of menstruation;
• prolonged menstruation - more than a week;
• lack of regular menstruation;
• the presence of bleeding that is not periodic; it may occur due to trauma to the cervix during intercourse;
• spontaneous ovulation of the second egg.

The female body is mysterious by nature and unpredictable. The beautiful half has the opportunity to become pregnant on any day of the cycle, since there are enough factors that knock down the menstrual cycle schedule. On the other hand, even a clear tracking of ovulation and sex on this day does not always lead to the desired meeting of the egg and sperm. How to accurately calculate the day of ovulation?

Determination of the most favorable days for conception

It is a well-known fact that conception occurs as a result of the fertilization of an egg by a sperm. However, not everyone knows that the largest cell in the human body lives for about 24 hours. If there is no meeting with the male germ cell, it dies, and pregnancy does not occur.

The optimal period for conception is ovulation - the moment the egg is released from the ovary. There are several ways to calculate these cherished days:

• measurements basal body temperature;
• ovulation tests;
• calendar method;
• according to your own feelings;
• ultrasound procedure.

We measure basal temperature correctly

Basal rates (core temperature) are measured in three ways:

• rectally;
• intravaginally;
• orally.

The internal body temperature is higher than the measurements in the armpit and more informatively reflects the physiological changes in the body. For calculation auspicious days For conception, rectal temperature is most often used.

This metric method is based on the fact that in the first days of the cycle, the rectal temperature is quite low, on the eve of ovulation it reaches the lowest possible values. After ovulation, when the corpus luteum begins to actively produce the hormone progesterone, which is a pyrogen, the temperature rises.

Pyrogens are special substances in the human body that affect the rise in temperature.

The difference between the temperature indicators is individual, on average it ranges from 05 to 0.8 ° C. If you make a graph of temperature drops, you can calculate the day of ovulation, as well as fertile (favorable for conception) and sterile days of the cycle.

To correctly calculate the day of release of a mature egg, regular measurements of the internal temperature are necessary, requiring strict compliance with the following conditions:

1. The temperature is measured immediately after waking up. In this case, you can not move, talk, and even more so get up. Even a mercury thermometer needs to be shaken the day before going to bed.
2. Before measurement, normal uninterrupted sleep is required - at least 5 hours.
3. Measurements of basal temperature are carried out in the period from 6 to 7 in the morning at one fixed time.
4. It is necessary to decide on the method of measurement (oral, vaginal, rectal) and carry it out for 5-10 minutes.
5. The thermometer is not recommended to be changed. If for some reason this happened, the day of replacement is marked on the graph.
6. Information obtained while taking oral contraceptives, drinking alcohol or being sick is not informative.
7. Changes in the situation, climate must be noted on the graph.
8. Information analysis can be carried out on the basis of at least 3 months of regular measurements.

All data is recorded in a special chart of basal temperatures. The cycle is clearly divided into two phases: first, the graph curve goes down with a drop in temperature, then two jumps occur - the temperature reaches a minimum, and then rises sharply to a level of 37.0 ° C and above. At this level, the indicators are kept until the onset of menstruation, after which they begin to decline again.
The basal temperature measurement chart clearly captures all temperature changes in the female body during the menstrual cycle.

Deviations from the standard type of schedule (there are no two phases or sharp fluctuations) indicates a deviation in the functioning of the reproductive system: a violation of the development of follicles or anovulation. However, this may also show the unfair implementation of all the rules for measuring basal temperature.

calendar method

You can calculate ovulation using the calendar method yourself or using various online calculators. These calculations are based on the fact that the day of the release of the egg for any cycle duration occurs 14 days before the next menstruation. The formula is simple: ovulation day = next period date - 14 days. With an ideal cycle of 28 days, ovulation occurs on the 14th day.

For example, this month, menstruation began on the 2nd day, therefore, the day of ovulation falls on the 16th. 2 + 28 \u003d 30 - the beginning of the next menstruation, 30–14 \u003d 16 - the date of ovulation. If the cycle is longer or shorter, the scheme is the same: add your cycle duration to the date of the onset of menstruation.

For example, the cycle is 21 days, the date of the first day of menstruation is also the 2nd number: 2+21=23; 23–14=9 - the date of the expected ovulation.

With a cycle of 35 days: 2 + 35 = 37 - depending on the length of the month, this is the 6-7th day, if we are talking about February, then the 9th day. 37–14=23 is the day of ovulation.

If the cycle is irregular, then the calculation method is as follows:

1. An analysis of all menstrual cycles per year is made.
2. The longest and shortest of them are selected.
3. From the number of days of the shortest, the number 19 (the first day of fertility) is subtracted, the longest - 10 (the last day of fertility).

For example, the shortest cycle was 24 days, the longest - 29. We calculate: 24–19=5; 29–10=19. Hence it follows that better days cycle for conception from 5 to 19. Below is a table in which you can see the most favorable period.

Table: the number of days favorable for conception, depending on the cycle

I use the calendar method almost from the first menstruation. At first it was a notebook where I made a calendar and marked the beginning and end of menstruation with circles. Then I got a more universal women's calendar from the antenatal clinic. Now, in the age of technology and smartphones, even a women's calendar is conveniently maintained using applications. I use Flo, I immediately liked the interface, it's very convenient to use. The application itself calculates fertile days and the date of ovulation based on the analysis of previous menstrual cycles. It makes life easier, but I cannot rely on the calendar method one hundred percent and do not advise others.

Every girl should keep a menstrual cycle calendar from the moment the first menstruation appears, so that when planning a conception, she clearly understands how her reproductive system functions and when ovulation occurs. However, this method is not considered effective enough because various factors shift the date of ovulation.

How to use ovulation tests correctly

A reliable way is the use of special ovulation tests. Their action is similar to pregnancy tests: the indicator shows a second strip if the level of luteinizing hormone is high, which indicates impending ovulation.

Manufacturers offer different variations of ovulation tests.

Modern pharmacology offers a wide range of tests, ranging from simple test strips to digital gadgets.

How to recognize ovulation by your own feelings

Girls who regularly monitor their own menstrual cycle note that during the period of ovulation there are accompanying sensations:

1. Vaginal discharge takes on a slightly different character. Cervical mucus is produced to ensure the fertilization of the egg, "holding" the sperm with its ductility. During the period of fertility, the discharge becomes cloudy at first, then more transparent. The consistency is sticky.
2. Increased sexual appetite.
3. The chest may swell.
4. Edema is likely.
5. Headaches and stomach aches from time to time.
6. There is increased irritability.
7. The sense organs are heightened.

These signs may accompany the fertile period, but they do not give a 100% guarantee of determining ovulation.

One of the most accurate ways to determine ovulation

Folliculometry (or ultrasound) allows you to accurately determine the date of ovulation, as well as whether this cycle was ovulatory. This version of ultrasound is similar to other gynecological ones, the study is carried out using an ultrasound scanner and sensor. It is recommended for those women who have serious menstrual disorders or do not become pregnant within a year with regular sexual activity.

Not every woman knows that pregnancy may not always occur when sexual intercourse occurs, but only at a certain period. Unfortunately, even doctors practically do not talk about the so-called fertile days. If a couple fails to conceive for one year or more, they are diagnosed with infertility. But it often happens that both the husband and wife are absolutely healthy, but pregnancy does not occur! What's the matter? It turns out that they simply can “not fall” on favorable days for conception. In addition, there are other factors that influence this process. Let's see what days you can get pregnant, how to determine that the body is ready for conception. But remember that women's bodies are different for everyone, and everything also depends on age, health and lifestyle, including the psycho-emotional state.

About cycles and egg maturation

Before we proceed to various calculations of favorable days for conception, we will nevertheless study how a woman’s body functions, or rather, how the reproductive system works.

Even in the womb of each girl, during the formation of organs, a huge number of eggs are laid in the ovaries. At birth and before puberty, the reproductive organs "rest". When the first menstruation comes, the girl becomes a girl, her body is now ready to bear and give birth to children. From then until menopause (comes at the age of about 45-60 years), the ovaries work cyclically, hence the phrase “menstrual cycle” appeared. It can last both the same for many years, and change under the influence of hormones, depending on the sufficiency of vitamins and minerals in the body, stress.

Below are examples on which day of the cycle you can get pregnant. The fact is that every woman's menstruation can be irregular, for example, the last time the cycle was 29 days, at the moment it is 31, and the next one can be short - only 24 days.

The first day of the cycle is always considered the day when bloody issues from the vagina. They can last from 3 to 7 days. During this period, the follicles located in the ovaries begin to mature. It is the follicle that contains the egg, which, upon meeting with the sperm, is fertilized. 14-16 days before the next menstruation, the follicle should mature and burst. Only then will the egg leave the ovary and travel through the tubes to the uterus, where it will meet with the sperm.

If fertilization occurs, then pregnancy will occur. At the same time, the ovaries stop producing follicles every cycle, and menstruation also stops. And if pregnancy does not occur, then with the next menstruation, the unfertilized egg will leave the body.

Mysterious ovulation

Sometimes women ask the question: “On what day after menstruation can you get pregnant?”. It is worth immediately answering that one should not calculate the period of conception by menstruation alone. After all, they can last from 3 to 7, or even more days or less. And spotting does not affect when you can start trying to get pregnant.

In the previous chapter, we talked about the maturation of the follicles and the release of the egg - this process is called ovulation. It lasts from the moment of rupture of the follicle until the death of the egg (if fertilization did not occur) and until conception (if everything worked out).

The egg itself can live from 1-2 hours to 1 day. Such a difference in the duration of her life depends on the age of the woman, physiology and genetics. It is impossible to guess how long the egg cell will live in this or that period - this is the sacrament of the female body.

Cycle phases

To make it easier to understand on which day you can get pregnant, it is advisable to study the basics of monthly cycles:

1. From the first day of menstruation to the day of ovulation - this is the first phase, which is called the follicular. During this period, the follicles mature to release the eggs. Follicles can be either one or many. The quality of ripening depends on the level of luteinizing hormone.
2. Then comes ovulation. This ends the first phase. This moment is considered the most favorable for conception.
3. Immediately the next day after ovulation, the second phase occurs, in which the corpus luteum forms. This phase will proceed normally with sufficient levels of the hormone progesterone, regardless of whether pregnancy has occurred or not.
4. If pregnancy does not occur, menstruation occurs 14-16 days after ovulation. It is worth noting that the second phase in a woman can be shorter or longer.

It happens that a woman's menstrual cycle is very short - only 21-23 days, and the second phase is slightly longer than usual. Therefore, sometimes the question arises of which day of menstruation you can get pregnant and is it possible.

How to understand that ovulation has come

Some girls and women in the middle of the cycle have pain in the left or right ovary, the stomach hurts as if menstruation begins. There may be a feeling of moisture in the genitals. But ovulation can come and be asymptomatic, or everything will happen so rapidly that you don’t even notice.

As a rule, a few days before ovulation, vaginal discharge appears - at first they are creamy white in color, then they become more transparent and liquid. On the eve and on the day of ovulation, these secretions should acquire the consistency of egg white. This means that the body is ready to safely accept spermatozoa, in addition, thanks to this mucus ( cervical fluid) The egg travels through the fallopian tubes to the uterus.

You can monitor your condition for several cycles to understand on which days of the cycle you can get pregnant.

When to try to conceive

Unlike the egg, which leaves the follicle once a cycle, sperm are produced in the male body constantly, from the moment of puberty to old age. In addition, spermatozoa in the body of the uterus can live up to 7 days, if the internal environment in the woman's body allows.

Thus, there is a chance of conception if sexual intercourse took place only 1 week before ovulation. Of course, in the case of compliance with all favorable factors, both from the male and the female side.

So what days can you get pregnant? It is assumed that only shortly before ovulation and on the day of ovulation. Therefore, you need to try to calculate fertile days so as not to miss the chance. Let's look at examples:

1. The duration of the cycle is 28 days. Presumably, ovulation can occur from the 13th to the 17th day, but ideally - on the 14th.
2. The duration of the cycle is 35 days. Ovulation can be expected from the 18th to the 22nd day.
3. Irregular cycle 28-35 days. AT this case tracking will take much longer, that is, from the 13th to the 22nd day.

Often a woman cannot determine when she is exactly ovulating, not only by the calendar method, but also by her own feelings. In addition, there may be very little secretion of cervical fluid.

Auxiliary methods for calculating ovulation days

You can get a special notebook, or you can use the ladies' application on your smartphone, where you should mark your basal temperature every day (measured rectally or orally) immediately after waking up.

In the first phase, the temperature will be lower than in the second. Between the two phases on the day of ovulation, the temperature becomes minimal, and on the first day after it rises sharply and lasts the entire progesterone phase.

In a few cycles, you can figure out which days you can get pregnant. It will be possible to calculate only on the basis of the previous graphs.

Determination of favorable days by tests

You can use an expensive, but more convenient method - an ovulation test. This test has a special tool that is applied to a paper strip that responds to an increase in luteinizing hormone (LH). When the test strip becomes as bright as the control, you can try to conceive. That is, the period of ovulation begins.

Often, women cannot deal with paper tests, so, if possible, a digital test with a smiley face is purchased. When there is every chance to conceive, the emoticon shows a smile.

Thanks to the tests, you can find out which days you can get pregnant. But it makes sense to carry out the procedure earlier than the expected day of ovulation.

Is it possible to get pregnant before menstruation

But if ovulation has already passed a few days ago, is there a chance? Theoretically, no. After all, the egg has already ceased its life. Therefore, attempts can only be started at the end of the next menstruation. That is, the period after ovulation and before critical days is safe for those who are not going to become pregnant.

There are in practice early and late ovulation, which is almost impossible to calculate. They can only be "caught" by tests or with the help of folliculometry in the ultrasound room. Only after such a study, a competent doctor can tell you which days you can get pregnant.

If conception does not occur

Every couple who wants to have children will think that after reading the article, they have already figured out why they cannot conceive for a long time. And now everything will definitely work out. Of course, if everything is in order with the health in the reproductive sphere for both, then everything should work out. But it happens that it doesn't. Why? There can be many factors. Among women:

• inflammatory processes in the pelvis;
• psycho-emotional stress, fears;
• lack of hormones, minerals and vitamins;
• Unhealthy Lifestyle.

In men, factors also relate to inflammation in the urogenital area, as well as poor spermogram and psychological reasons. If the causes are eliminated, then conception will definitely occur.

You learned on what day after menstruation you can get pregnant, and how to correctly determine fertile days in general. We wish you good luck and the birth of a healthy child.

Approximately from the age of 12–13, girls begin menstruation, which indicates the readiness of the reproductive system to reproduce offspring. The menstrual cycle is a complex phenomenon, and includes a lot of related processes. One of the most important in terms of the possibility of getting pregnant is ovulation. Let's find out exactly how it is connected with conception and when there are the greatest chances of becoming a mother.

What is ovulation

As part of the menstrual cycle, cyclical changes occur in the female body, stimulated by the production of hormones. So, in one of the ovaries, thanks to the follicle-stimulating hormone, the dominant follicle matures, inside which the egg is located. Approximately in the middle of the cycle, it breaks, releasing a cell ready for fertilization, and this phenomenon is called ovulation. After the egg moves through the fallopian tube towards the uterus, where favorable conditions have already been created for further implantation, subject to fertilization. If conception does not occur in the current cycle, then the egg dies, and, together with the exfoliating lining of the uterus, is removed from the body through menstrual bleeding.

Ovulation is the process of release of an egg ready for fertilization from the follicle in the ovary.

Ovulation and conception

Ovulation is directly related to conception, because if a mature egg does not come out of the ovary, then it will not work to get pregnant.

When planning a replenishment, many expect to get a positive result from the first time, but this is not always possible, because successful conception depends not only on the fact of having a ready egg. In medical science, it is believed that trying to have a child for one year is the norm, and only if after 12 months it is not possible to achieve what you want, you should contact specialists to clarify the reasons.

With an average cycle duration of 28 days, the rupture of the follicle occurs approximately in its middle, on days 13–15, but deviations from this figure are possible. Calculating the day of ovulation, relying solely on the stable order of menstruation, is not worth it, this rarely provides reliable information necessary for conception. The following methods are considered the most reliable:

• usage . The test strips measure the level of luteinizing hormone in the urine and high value will talk about the release of the egg. The method is quite accurate, but it requires daily conduction and recording of results to draw up a dynamic picture, which is not always convenient and quite costly from a financial point of view;
  A home ovulation test should be carried out over time to monitor changes in the amount of luteinizing hormone
• folliculometry - ultrasound examination of the ovaries. Allows you to find out if ovulation occurs, and when the best moment for conception comes;
  Folliculometry allows you to accurately determine the fact of the onset of ovulation in a woman
• basal temperature charting is the easiest and most commonly used method at home. Every morning at the same time, without getting out of bed, it is required to measure the temperature in the rectum and fix it on the graph. On the border between low and increased rates temperature and ovulation occurs.
  Basal temperature charting should be done gradually by measuring the temperature in the rectum every morning

Best days to conceive

The definition of ovulation is of great importance for the success of conception, since the female egg lives for a short time - from 12 to 36 hours, after which it dies and there will be no chance in this cycle. Yes, most auspicious days for trying to get pregnant are considered:

• directly the day of ovulation - the probability of conception reaches 34%. In this case, the spermatozoa must be active enough to have time to reach the goal;
• 5 days before ovulation. This figure is due to the viability of spermatozoa - in some cases, they can remain active in the reproductive system of a woman for exactly 5 days. Sexual intercourse during this period has an increasing chance of fertilization - from 10% 5 days to 31% 1 day before ovulation;
• 1 day after ovulation. After the release, the phase of a rapid decline in fertility begins, since the egg dies rather quickly. There is a chance of getting pregnant during this period, but it is not too high. After 1-2 days, a period of absolute infertility sets in, which lasts until the end of the next menstruation, and it is impossible to get pregnant either a few days or a week after the release of the cell.

It is impossible to get pregnant without ovulation, since there is no basic condition for conception. It is important to understand that the egg may not mature every cycle, on average, a woman produces 10-11 cells capable of fertilization per year, and the rest of the cycles are anovulatory.

Safe days or periods of minimum fertility

There is a method of preventing unwanted pregnancy by detecting ovulation (called calendar). It is based on the calculation of the day of the release of the egg and the exclusion of sexual contact during this period. This approach is inherently really effective, since in each cycle there are safe days when there is no chance of getting pregnant at all - this is the time from the beginning of the cycle (onset of the next menstruation) to the period of 5 days before ovulation, and the interval from 2 days after the release of the egg to next menses. It's simple and logical: no live egg - no pregnancy. However, this method has its downsides. So, the timing of ovulation can shift in each cycle under the influence of a lot of reasons, and it is impossible to know exactly when exactly the follicle will burst, and therefore calculate the “dangerous” period before this event. The approach is effective only in a situation where the fact of ovulation is known reliably and more than a day and a half has passed.

The calendar method of contraception involves the calculation of safe days with no chance of getting pregnant

Signs of successful conception after ovulation

When the spermatozoon reaches its goal and fertilizes the egg, the stage of implantation begins - insertion into the prepared loose lining of the uterus and fixing there for further division and development of the fetus. It takes some time, therefore, immediately after intercourse during ovulation, it is impossible to find out about the fact of conception, since the corresponding changes in the female body have not yet begun to occur. Pregnancy can be reliably established based on the results of a blood test taken over time with a certain interval to establish the level of human chronic gonadotropin (hCG) and according to ultrasound data. At the same time, there are a lot of signs that cannot be considered unambiguous, but they, especially in the aggregate, can be highly likely to be evidence of a conception that has occurred:

• delay in the onset of menstruation (if the introduction of a fertilized egg into the walls of the uterus has occurred, then there will be no rejection of the lining, and therefore menstruation);
• swelling and soreness of the mammary glands;
• implantation bleeding - a small discharge of blood in the absence of the onset of full-fledged menstruation. During the introduction of the egg, the vessels in the uterine wall can be injured, which will cause short-term bleeding;
• a sharp "dip" (decrease) in the basal temperature chart 2-5 days after ovulation;
• slight malaise due to a decrease in immunity (this is necessary so that the embryo is not rejected);
• increased fatigue, drowsiness, weakness;
• slight pulling sensations in the lower abdomen, warmth due to a rush of blood.

After conception. the egg moves to the uterus, where it is implanted in its wall

At home, if you suspect pregnancy, you can do a test for the content of hCG in the urine. If it is negative, do not be upset, since the sensitivity of such an express method may be insufficient for early term, and it is worth repeating it later.

Pregnancy tests behaved differently for my friends. The cherished two strips appeared to one girl on the very first day of the delay, the second one had a distinct strip for almost 10 days, until she passed a blood test to detect the same hCG and found out that she was pregnant. In my case, a pale strip of a positive result was noticeable 3 days before the expected menstruation, and it was present only on 2 out of 4 tests purchased from different manufacturers.

Ovulation occurs, but pregnancy does not occur - causes

The presence of a mature egg is one of the main conditions for conception, but far from the only one. The process of creating a new life is very complex, and its success depends on a large number of factors. If a woman ovulates, but pregnancy does not occur, then this may be the result of the following conditions:

• hormonal disruptions. They may exist due to problems with the endocrine system, due to a past illness or nervous tension;
• inflammatory diseases in the reproductive system of both women and men;
• obstruction of the fallopian tubes, due to which the egg cannot reach the uterus;
• infection of the uterus;
• endometriosis - the spread of endometrial tissue outside the uterine cavity, which becomes a source of formation of adhesions, cysts, scars, inflammatory processes that prevent pregnancy;
• underdevelopment of the endometrium - too thin a layer does not allow a fertilized egg to hook on and implant;
• insufficient number of healthy and mobile spermatozoa in the male ejaculate.

Gallery: reasons for the lack of pregnancy with intact ovulation

Inflammatory processes in any of the elements of the female reproductive system can prevent pregnancy. One of the common reasons for not getting pregnant during ovulation is low sperm activity in men. Endometriosis is the spread of endometrial tissue to areas outside the uterus.

Lack of ovulation - what to do?

In a situation where a woman has, first of all, specialists are taken to find out the reasons for this condition. This can be due to an infectious disease, increased stress on the psyche, hormonal failure, and even insufficient weight (less than 18% body fat). After identifying the source of the problem, measures are taken to eliminate it, which will be determined on an individual basis. It could be.

So, during each menstrual cycle in a woman's ovaries. She leaves the ovary and begins to move along the fallopian tube towards the uterine cavity. If at this time it meets with a sperm, fertilization occurs and further, if favorable, pregnancy. If such a meeting does not occur, the egg dies. Oddly enough, even knowing the general pattern of pregnancy, many men and women have absolutely no idea when sex is without consequences.

Get it done in 48 hours

You will be surprised, but the egg retains the possibility of fertilization for only two days from the moment it leaves the ovary. If during this period you do not meet with a spermatozoon, there can be no talk of any pregnancy. Simply put, a woman is able to conceive an extremely short period of time. These most “dangerous days”, as they are commonly called, are ovulation or the middle of the menstrual cycle. Sexual contact during the release of the egg and the next two days is the most dangerous in terms of possibility. A logical question arises, why then should contraception be used with every sexual contact? Everything is simple. Despite the fact that the life span of the egg is very short, the situation is influenced by many indirect factors, which are not always taken into account.

Before and after

Firstly, not every woman's menstrual cycle is regular and works like clockwork. The hormonal background can change due to moving to another region, illness or severe stress, and all this automatically shifts the menstrual cycle up or down. So it turns out that even with a regular cycle and a predicted date of ovulation, you can miscalculate and not get into a safe period.

Another factor that must be taken into account is the ability of spermatozoa to maintain their viability inside a woman's body for several days after intercourse. That is, you can have sex even on quite safe days, and the male reproductive cells will simply wait for the release of the egg already in place. That is why gynecologists recommend the most careful protection 4-5 days before the expected start of ovulation and another 3-4 days after - just in case. After all, it also happens that you expect the middle of the cycle one day, and it comes a little later.

But about a week after ovulation, the safest days for conception begin. The egg, whenever it leaves the ovary, has already died, so the sperm simply have nothing to fertilize. Before the onset of menstruation, during it and 2-3 days after, you can have sex without fear.

Many women dream of getting pregnant, but they do not always succeed. This is influenced by many factors, one of which is the menstrual cycle. It is important to understand that for conception, gynecologists allocate certain days when there is a high probability of fertilization of the egg.

What is pregnancy?

Pregnancy is the state of a woman in which a fetus, or embryo, gradually develops and gestates in her body. It occurs at the time of male female germ cells, the process occurs in the fallopian tube.

Pregnancy lasts 9 months, or 40 weeks, after which it ends with childbirth.

You can not conceive a child on all days of the menstrual cycle. Allocate safe days, as well as the time of egg fertility, that is, its release, in which you can become pregnant.

When is the most likely to become pregnant: how to calculate?

All women of reproductive age should be aware of the days during which they can become pregnant.

As a rule, this time falls in the middle of the monthly cycle, that is, approximately on the 7-10th day of the end of the last menstruation, unless, of course, your regular monthly cycle is 28-29 days. To calculate the exact days, it is necessary to take into account the regularity of menstruation, as well as the duration of the menstrual cycle by day. As a rule, not all women have a regular cycle, which lasts 28 days. In this case Fertility days can be calculated as follows:

1. Take your calendar with menstrual cycles highlighted. You need to calculate with the number of days for the last six months.
2. Subtract 18 from the shortest number. For example, the shortest cycle is 23 days, it turns out: 23-8 = 5 therefore, from the 5th day of the menstrual cycle, you can become pregnant.
3. To check the last possible fertile days, you need to look at the longest menstrual cycle. From this number it is necessary to subtract 11. Let's calculate on an example. Let's say the longest cycle is 30 days, so: 30-11 = 19. Thus, the 19th day of your menstrual cycle and the days after are safe, that is, you cannot get pregnant during them.
4. From our example, we can conclude that the probability of getting pregnant starts from the 5th day of the menstrual cycle and ends on the 19th day.

What are fertile days and ovulation?

The greatest chance of getting pregnant is just on fertile days and, of course, during the period of ovulation, which lasts 1-2 days . We calculated the days with fertility, that is, the probability of getting pregnant, using an example. On such days, the woman's body is maximally ready for fertilization.

Ovulation is the release of an egg ready for fertilization from the ovarian follicle into the fallopian tube. The day of ovulation occurs, as a rule, on the 10-14th day of the menstrual cycle.

As a rule, spermatozoa in the fallopian tube can live up to 5 days. Once in the female body during fertility, they can fertilize an egg a few days later during the ovulation period.

What days are you unable to get pregnant?

During menstruation, there is not even the slightest chance of becoming pregnant.

For example, with a cycle of 28 days, safe days can be considered: 1-7 days and 18-28 days of the menstrual cycle. If the monthly cycle is short and is 21 days, then 10–21 days can be considered a safe period. With a long cycle, which is more than 30 days, you can not get pregnant for 25-35 days, as well as the first 14 days.

Is it possible to get pregnant after fertile days?

Many women do not know whether it is definitely impossible to get pregnant before menstruation. In most cases, no, unless, of course, a woman has ovulated twice during her cycle. As a rule, such situations can occur with irregular periods, as well as in young girls whose menstrual cycle is just being formed.

The chance also increases for those ladies who have sex with the same partner.

Chances of getting pregnant right after your period

What factors influence conception?

It is worth noting that only completely healthy women who have sex with a healthy partner can get pregnant. The following factors affect the likelihood of conception:

• the age of the woman (up to 35 years, the likelihood of becoming pregnant is greater);
• sperm activity;
• the presence of ovulation;
• absence of health problems and STDs (sexually transmitted diseases);
• regular menstrual cycle;
