The likelihood of flying after menstruation. How to deal with spontaneous ovulation

It is unlikely that there is such a girl who at least once would not wonder if it is possible to get pregnant immediately after menstruation. Desire to insure against unwanted pregnancy is inherent in many couples nowadays, because a child is a big responsibility.

Even though there is now a large number of methods of contraception, from which each girl can choose the one that suits her, it is still a frequently asked question whether pregnancy is possible immediately after menstruation. To answer it, you should remember how the fertilization of the egg occurs. Every month, at about the same time - usually it is the 12-15th day of the cycle, the so-called ovulation occurs in the female body - the maturation of the egg, the fertilization of which can lead to pregnancy.

Due to the fact that each organism is unique, ovulation in a particular woman can be shifted either to the beginning of the cycle, or closer to its end. Each woman can herself, or with the help of a doctor, calculate the days on which her ovulation will fall. It is important to remember that during the cycle, not one, but several eggs can be formed with a difference of several days. That is why you can not have any guarantees for the presence of "safe" days for a girl. The maximum probability of pregnancy remains precisely during the maturation of the egg in the middle of the cycle.

But, according to experts and a number of conducted contemporary research, the possibility of pregnancy immediately after menstruation remains quite high. This may happen in the following cases: when a second, additional egg occurs, the maturation of which occurred precisely at the time of completion critical days or if ovulation, under the influence of any external or internal factors, has shifted and arrived ahead of schedule. Pregnancy can occur at any period of the cycle in the event that it is not regular, as well as with too long or too short periods.

In the above cases, there is no guarantee that the egg in the body of a woman will mature constantly at the same time periods and her " combat readiness"will not fall on the days immediately following the cessation of menstruation. There can be no categorical answer to the question of the occurrence of pregnancy on any specific days; for each woman, the possibility of conception depends on her physiological features. There are couples who to this day are protected by the "calendar" method, and he has never let them down, but there are also those who endured, gave birth and raises a child, having conceived it precisely on the days of the cessation of menstruation.

Even perfectly healthy women may experience a failure or disruption of the cycle. You should always remember about the possibility of pregnancy at the wrong time. In the event that conception is not planned in the near future, experts recommend using proven methods of contraception.

Gynecologists say that under certain circumstances, pregnancy after menstruation is quite possible. There is always a chance of conception, even if these are minimal values. It is worth noting that spermatozoa can live in a woman's body and remain active for a week. Therefore, even if ovulation occurs at the right time, they may well wait for it and fertilize the egg. The way out of such situations is simple - protection by effective means.

There are also the first signs of pregnancy after menstruation, however, these signs do not depend on when the conception occurred, they will always be the same. First of all, this is the absence of menstruation on time, or very meager discharge. This should already alert the woman, after which she is recommended to take a pregnancy test to be sure that it is she, and a subsequent visit to a specialist. Making an appointment with a gynecologist is required even if the tests show negative result. After all, the absence of menstruation indicates that the female body has experienced hormonal disbalance requiring medical intervention.

Also, signs of pregnancy can be considered pain in the chest and a noticeable increase in it, possibly a slight darkening of the nipples. This is due to the fact that the body begins to prepare the breast for its functions after the birth of the child, namely for feeding. Signs of pregnancy include irritability, depression for no apparent reason. Lethargy appears due to the fact that the body comes hormonal changes He is getting ready to bear the fetus. You can independently detect the presence of pregnancy not only through the test, but also in determining basal body temperature. This method can talk about the presence of an embryo even at the initial stages.

For exact result it is required to measure the temperature every morning for several days in a row. In the event that the thermometer shows at least 37 degrees every day, we can talk about the presence of pregnancy. Unfortunately, even this diagnostic method may have errors due to individual features organism, or in case of non-compliance with the rules for measuring temperature. by the most exact way to determine the onset of pregnancy remains a visit to the gynecologist. And he, in turn, will give a referral for a blood test for hCG and an ultrasound scan.

Experts have found that about 1-2% of women are affected by pregnancy immediately after menstruation, but one can never say with full confidence Who exactly is included in these few percent. Those who are in this moment does not want to conceive, you should always remember these numbers.

The probability of pregnancy remains throughout the cycle and depends on the characteristics of the organism of each particular woman. That is why, if the appearance of a child is undesirable, one should not forget about contraception on any day.

Today, many interrupted sexual intercourse is used as a method of contraception. It is for this reason that they are primarily concerned about the question, after how many days after menstruation can you get pregnant? The same applies to couples who do not protect themselves at all and dream of a child - it is necessary for them to know exactly at what period of the month a pregnancy can occur, since these days it is most relevant to exercise sexual activity. Let's consider this question in detail.

On what day after menstruation can you conceive a baby?

It should be noted right away that pregnancy can only occur during ovulation - it falls in the middle of the cycle (although it all depends on individual characteristics). female body).

For the first time a couple of days after the end of menstruation, it is almost impossible to get pregnant - this is due to the fact that internal environment the uterus as well as the vagina is very unfavorable for spermatozoa.

You can find out exactly which days you can get pregnant only if the woman has a stable menstrual cycle. Consider what can be done in order to know exactly when dangerous and safe days come:

1. We start a calendar where we will mark all the data on menstruation. Beginning, end, symptoms. It is important to consider that if the difference between the longest and the longest short cycle more than 6 days - in this case, the calculations will not be effective, and it will not work to find out when ovulation occurs using the calendar method.
2. So, next we need to take the shortest and also the longest cycle. In the first, you will need to take 18 days, and in the second - 11. It is these days that will become for you the beginning, as well as the end of the ovulation period.
3. After the specified period, the likelihood that you can become pregnant becomes lower and lower. Experts have long found out that the safest days are before menstruation and after - about 2 days, although again, it all depends on the characteristics of the female body.

Important! The shorter your cycle, the more less days when pregnancy is excluded. For example: the first day of the cycle is the beginning of menstruation, the first day. If a woman has the shortest cycle for 23 days, and the longest - 27, then on day 5, the onset of ovulation can already be noted. But with long periods, a favorable day for conception may coincide with last days, while continuing until the 16th.

It is very important to remember that calendar method contraception can not be one hundred percent! The cycle can change, which means that the date of ovulation can also shift. The same applies to the universal calculation plate, when you can have sex without fear of getting pregnant - each woman has her own cycle, its duration fluctuates, so you need to calculate everything yourself. It is noteworthy that at the moment there are special calendars where you can record data about your menstruation, they also show auspicious days for conception, but do not give a 100% guarantee.

What are the chances of getting pregnant before or after your period?

Even though the probability is very low, it still remains. The first two days can be considered safe, but only taking into account that the cycle remains stable, and no errors were made in the calculations.

As for the days after menstruation has passed, almost any woman can become pregnant at this time. The exception is those who have a long cycle, but at the same time menstruation does not last long, the period when you can get pregnant starts a little later.

So, let's consider which phases are normal for healthy woman the menstrual cycle consists of:

1. Follicular. The first half of the cycle, it is at this time that thanks to FSH (the so-called special hormone) in one of the ovaries begins to mature dominant follicle, later, an egg ready for fertilization by a spermatozoon will come out of it.
2. Ovulation. During this period, LH begins to be produced - also a hormone, but under its influence, an already mature egg moves into the abdominal cavity.
3. luteal phase. Progesterone begins to be produced - the body prepares for probable offensive pregnancy. Suitable conditions are created in the body for the fertilized egg to successfully implant and develop.

Every month, all these phases are repeated, and as we can see, each phase is responsible for certain hormone. The first and third phases last 13-14 days, but ovulation does not last long - about 2-3 days.

A woman can become pregnant only during the period of ovulation - therefore, only a few days a month. The egg comes out to meet the sperm, and if everything goes well, then he fertilizes it. Further, if the circumstances and health of the woman permit, then fertilized egg gradually move into the uterine cavity. Pregnancy occurs as soon as the fertilized egg attaches to the mucosa.

Can there be deviations from the norm?

If a woman is absolutely healthy, then she ovulates every month. Normally, the cycle lasts from 20 to 35 days, it depends on its duration on which day the favorable days will fall for the possibility of getting pregnant.

Nevertheless, it is impossible not to note the fact that sometimes even in healthy women the menstrual cycle can go astray, and there are several reasons for this:

• hormonal imbalance;
• STIs - infections that are sexually transmitted;
• transferred abortions;
• surgical operations;
• the presence of common chronic or acute diseases;
• changing of the climate;
• transferred stressful situations.

Are there any symptoms during ovulation?

Not always, but some women feel quite unpleasant symptoms with the onset of ovulation. As a rule, it is cutting or nagging pain- and it falls precisely on the ovary where the egg has matured. Experts say that this moment is directly related to the fact that there is damage to the mucosa, as well as its surface. Usually, discomfort short-term - no more than a day, but it also happens that a woman experiences tangible discomfort. If the problem continues from cycle to cycle - in this case, you will need to consult a gynecologist, this may well indicate some diseases.

How else can you understand that ovulation has come?

We have considered the most simple and convenient way definition of ovulation, but it is not accurate, that is, a woman who does not want children can still become pregnant. The same applies to the fair sex, who dream of having a baby - it is just as important for them to calculate the moment when the probability of pregnancy is highest. So, let's look at a few more methods that will help determine the onset of favorable days.

Another common method is to measure basal body temperature. That is, it is necessary to measure the temperature in the rectal area, while it is necessary to apply the usual mercury thermometer. This should be done immediately after waking up. In the first half, the temperature is usually 37 degrees. The closer to the onset of ovulation, the higher the temperature will be. Before ovulation, it will drop a little, then there will be a jump of 0.5 degrees at once - this means that the egg has come out and is ready for fertilization.

The ovulation test is the most accurate and convenient. In a pharmacy, you can easily purchase special tests that determine the output of the corpus luteum by the concentration of hormones in the urine - it is very simple to check with them whether the onset of ovulation has occurred, and the result will be reliable. The only negative is that the tests are quite expensive.

Video: is it possible to get pregnant after menstruation?

The probability of getting pregnant immediately after menstruation is quite high. Therefore, you should not rely solely on the calendar method of contraception. There are factors due to which the calculations on safe days are unreliable, and pregnancy occurs immediately after the end of menstruation.

Usually female cycle lasts 28 days. This is the basis of the popular method calendar contraception when a woman calculates safe time for unprotected sex. The first days after the cessation of discharge are considered safe.

At the slightest cycle failure, the likelihood of getting pregnant after menstruation increases dramatically.

The danger of "safe" days

In the 20th century, this method was one of the most popular means protection. Doctors assured the patients that the likelihood of getting pregnant immediately after menstruation was minimal.

And today it is believed that three days before the end of the cycle and 48 hours after menstruation is the safest period for unprotected intercourse. However, there is a risk of conception on the second or third day after menstruation.

In addition, it is not always possible to correctly calculate safe days, which increases the likelihood of conceiving a child.

Phases of the cycle for conception

Many women doubt whether it is possible to get pregnant on the 21st day of the cycle, and count the safe days due to the physiology of the body.

The cycle ends and begins on the first day menstrual bleeding. It usually lasts four weeks, but can vary from three to five weeks.

The menstrual cycle includes several phases:

1. Follicular. The longest phase (lasts 10-18 days). In this phase, the main follicle, the dominant one, grows in the ovary. It prepares for ovulation and carries an egg for fertilization.
2. Ovulatory. The follicle is ready, ovulation occurs, that is, the destruction of the follicle. A mature egg is waiting for a meeting with sperm, moving along fallopian tubes towards the uterus. "Waiting" lasts about 24 hours. That is how long the egg lives, and with unprotected intercourse these days there is Great chance get pregnant.
3. Luteal. The main role in this phase is assigned to the uterus, which is preparing once again to receive a fertilized egg. This occurs under the influence of the corpus luteum remaining in the ovary after the destruction of the follicle. It releases progesterone into the body of a woman - the main hormone responsible for normal course pregnancy. If conception has occurred, the endometrium will be prepared for implantation (implantation of the embryo). An egg that does not meet with a sperm cell dies within 24 hours. After the death of the egg, conception becomes impossible.
4. Menstrual. If conception does not happen for some reason, the corpus luteum ceases to exist, progesterone is not produced. The mucous membrane is destroyed, which leads to menstruation, cleansing the uterus and preparing it for a new ovulation. Together with blood secretions the endometrium and the remnants of the egg are removed from the body.

1-2 cases out of a hundred

During menstruation and the day after, the hormonal background prevents conception during intercourse without the use of contraception. That is why, if a woman is interested in whether there is at least a minimal chance of becoming pregnant after menstruation, doctors give a negative answer.

However, there is a small possibility of pregnancy immediately after the end of menstruation (1-2 cases out of a hundred). It seems illusory: even in periods of the cycle favorable for fertilization, conception occurs only in 30% of cases.

And yet there is a risk of conceiving a child on safe days. female physiology leaves a small chance of conception on the first day of the cycle, and on the tenth. Protecting herself according to the calendar method, a woman must take into account everything.

Without limits and rules

There are many women in the world, monthly cycle which is constantly shifting. This is due to the nature of the work hormonal system. In this case, it is difficult to predict which days ovulation will occur. The safe interval is defined incorrectly. Monthly with such a cycle are with a shift in the week. For such women, protection using the calendar method is useless.

Too short cycle

The menstrual cycle in women is different duration. If it is too short, it is possible to get pregnant on the 10th day from its onset, because calculation method contraception is based on calculations of "standard" phases. With a short interval between menstruation, it happens that the egg matures at the moment the bleeding ends, therefore, with sexual contact without contraception, you can quickly become pregnant immediately after menstruation.

Cycle too long

Pregnancy on the first day after the cessation of discharge becomes possible due to prolonged menstruation. Normally, the discharge lasts about five days, but there are times when menstruation lasts a week or longer, and the maturation of the egg occurs during this period. This is actually no longer menstruation, but menstrual-like bleeding during various diseases female genital area. The egg is then ready to travel to the uterus before the end of the discharge. Spermatozoa in the genital tract of a woman can retain their ability to fertilize up to a week. Therefore, the chances of conception are quite high.

Two eggs at the same time

Occasionally, there are cases of maturation in one cycle at the same time of two eggs, ready for fertilization. With spontaneous ovulation, pregnancy can occur during menstrual flow and immediately after their termination. If the eggs mature together or with a short time interval, then the question of whether it is possible to get pregnant after menstruation is answered in the affirmative.

Is the partner to blame?

Fully trust the method of calculation and determination dangerous days not worth it for women with a cycle of standard length. After the cessation of menstruation persists minimal chance get pregnant.

In such cases, the “fault” lies with the sexual partner: in a man, spermatozoa can be characterized by a special, increased mobility, survivability. They can live and retain the ability to conceive in the genital tract of a woman for up to a week, waiting for the appearance of an egg ready for fertilization. Unprotected intercourse can take place on calendar-safe days, and conception will occur later, during the "fertile window", a week after sexual contact.

Imaginary periods

It happens that at the time of ovulation, conception occurs, the embryo settles in the uterus, and menstruation still comes. This is not a real menstruation, but bleeding due to progesterone deficiency and partial placental abruption. The woman creates the illusion that the calendar method still worked. Upon learning of the pregnancy, she attributes everything to a failure of the contraceptive method, although in fact the conception happened at the due time for this, and not during safe days. After the ultrasound, it becomes clear that the actual gestational age is longer than expected.

For menstruation, you can take other bloody discharge, which may occur due to the development of some kind of disease of the genital organs, for example, cervical erosion. Bleeding may occur due to too much activity of the partner during sexual contact. If such discharges are perceived as menstruation, then with the calendar calculations of the safe period, the likelihood of conception increases dramatically.

Bloody discharge, similar to menstruation, is also found in inflammation of the uterus, adenomyosis and other pathologies of the female genital area.

Any change is a failure.

Changes hormonal background women can lead to an error in calculating safe days and to the development of pregnancy. Possible reasons many hormone imbalances

• taking medication;
• unbalanced diet;
• diet and a sharp decline weight;
• acute infectious diseases;
• exacerbation of any chronic pathology;
• large physical exercise and stress;
• lactation.

Many cases have been recorded when a vacation trip ended in an unplanned pregnancy. After all, these are joyful excitements that can bring down any cycle. Therefore, you should not trust only calculations during such a period. If it happened at the same time menstrual failure and unprotected sexual contact, this may be enough to conceive.

Contraception without calculations

"Calendar contraception" is not reliable protection women from unwanted conception. IN modern world there are many methods of contraception that prevent pregnancy in almost 100% of cases.

The contraceptive method of counting has long proven its unreliability. Many reasons can bring down the menstrual cycle, and it will not be possible to determine the safe period correctly.

With the past scarcity of quality products, and sometimes their complete absence in the market, women were forced to look for home-grown ways to avoid unwanted pregnancies. One of them is associated with natural features. And even now, under certain conditions, some people consider the calendar method acceptable and sufficient for protection. To understand whether it is possible to get pregnant immediately after menstruation or if you should not be afraid of this, you should understand in detail the functioning of the female body during this period.

What happens during menstruation

The menstrual cycle of a healthy woman can be divided into 3 periods of development:

• Follicular. In the ovary, out of many others, a dominant follicle is determined and grows, which then turns into a mature egg;
• . The female cell becomes as ready as possible for fertilization and enters the uterine cavity. In this state, she stays for 2-3 days. The endometrial layer during this period becomes thicker, preparing to receive the embryo. This is the time when the probability of pregnancy is maximum;
• luteal. The ovum, which unites with the sperm, attaches itself to the internal cavity uterus, where the embryo begins to develop. If fertilization does not happen, it occurs reverse development, as well as the rejection of the upper layer of the mucosa of the organ in the form of menstruation and its replacement with fresh cells.

The process is regulated by a change in the concentration in the body responsible for the maturation of the egg, the attachment of the embryo to the inner lining of the uterus. Theoretically, the probability of getting pregnant after menstruation is close to zero. Real life surprises gynecologists with other examples.

When is it possible to conceive after menstruation

Pregnancy after menstruation in some cases is quite real. Many women, not knowing the characteristics of their body or not attaching importance to them, found themselves in anticipation of their future children in this particular period of time. This is possible under the following circumstances:

• . It's peculiar young girls who have recently begun menstrual bleeding. In such cases, the cycle, and hence the time of ovulation, can remain “floating” for a couple of years. It is simply unrealistic to calculate the days of egg maturation. Perhaps that is why there are so many underage mothers in the world who mistakenly counted on the calendar method of protection;
• Short menstrual cycle. If it is only 21 days or less, the egg matures very quickly and is made ready for connection with the sperm immediately after menstruation;
• Long periods of time. When the process of replacing the old layer of the endometrium is delayed up to 7-8 days, it is likely that by the end of this period a new egg will mature. The question of what days you can get pregnant after menstruation has an answer in this situation - on the very first day;
• The maturation of more than one egg at the same time. It occurs predominantly in young, healthy women, although the reasons similar phenomenon are not exactly known. It has only been established that the factor of heredity has its significance here;
• mistaken for menstruation. This happens with inflammatory diseases of the internal female organs or too active sex. A woman may incorrectly calculate the date of ovulation and take her "fertile window" for a safe day, in the sense of the possibility of becoming pregnant;
• Spontaneous ovulation. This inexplicable phenomenon means the maturation of the egg on any day of the cycle. Then conception can occur after menstruation. When you can get pregnant in such a case depends more on the date of unprotected intercourse.

How to identify "safe" days

You should know that the calculation can be very approximate, and it is quite difficult to find out for sure if you can get pregnant after menstruation. Given the process of birth and maturation of the egg, its entry into the uterus, with a 28-30-day cycle, ovulation will occur on the 14-16th day. This does not mean the impossibility of getting pregnant during this entire period. A layer of the endometrium is already growing in the uterus, becoming looser for the best fixation of the embryo.

An important and sometimes decisive factor is the extraordinary vitality of spermatozoa. They can remain active for several days, sometimes more than a week. If there are many such active spermatozoa in the seminal fluid, the probability of conception increases many times over. This means that with unprotected sex on the 6th or 7th day of the 30-day menstrual cycle fertilization is possible.

If a woman's menstruation comes every 21-25 days, how quickly you can get pregnant after menstruation is easy to find out according to the same parameters: 1-3 days after they end. Just in this period of time, under these circumstances, ovulation will occur, and therefore, conception is likely.

But even this is not enough to make sure that pregnancy will not happen. A woman's lifestyle can also play a role in the process and timing of ovulation, accompanying illnesses. For example, thyroid problems cause hormonal changes that affect reproductive function. Experienced women, when deciding how many days after menstruation can not be protected, take into account, first of all, the nature of their monthly discharge. But not only them. Those who have relied on the calendar method of protection still have to be measured and done regularly, since this method of avoiding conception cannot be called reliable.

When is it advisable to use the calendar method of protection

It is worth saying that even in the absence of the above signs, avoiding pregnancy by calculating “safe days” is a rather unreliable method. It is worth using it only when it is the only possible one:

Which days are the most favorable for conceiving a child, and which, on the contrary, are the safest. ... I do not understand, you can get pregnant only after menstruation?

What day is ovulation. Ovulation after menstruation occurs 10 to 18 days later. ... Is it possible to get pregnant after ovulation.

Can you get pregnant right after your period? This question is relevant not only for partners planning to conceive. Possible pregnancy couples who do not use contraception and use the method of calculating safe days are afraid. PA after menstruation can end in conception, but this is not always the case. Fertilization depends on three factors:

• the day of the cycle on which the contact took place;
• the state of women's health;
• indicators of male fertility.

A woman's menstrual cycle is a change of state reproductive organs within a certain time period, controlled by the work endocrine apparatus. It is considered from the first day of bleeding to the beginning of the next. On average, it lasts 26-28 days. Depending on the individual characteristics of the organism or under the influence external factors the cycle can be shortened or lengthened.

It is considered normal if the interval is at least 21 and not more than 35 days. In a healthy girl, the moment of opening the follicle occurs at the same time after the onset of bleeding, which indicates the regularity of the cycle. Specialists identify the main phases that help to understand the process of fertilization and determine safe days.

• Menstrual - starts from the first day spotting and continues until they are completed. At different women ranges from 3 days to a week.
• Follicular - begins after the end of menstruation and lasts until the maturation of the dominant follicle. It can vary from several days to 2 weeks.

• Ovulatory - the period of life of the egg. Duration most fertile period in the fairer sex, it is usually the same and is no more than 2 days.
• Luteal - activity of the gland internal secretion. corpus luteum lives about 12-14 days after ovulation. This phase of the cycle, unlike the menstrual and follicular, should be stable in all healthy girls.

You can get pregnant during the period of ovulation and shortly before it. The activity of spermatozoa is such that they are able to survive in the pelvic cavity of a woman for several days. Therefore, if PA took place after menstruation, even before ovulation, sperm may well “hold out” until it.

What is the chance of getting pregnant after menstruation

Perennial obstetric practice proves that some couples get pregnant quickly after menstruation, while others cannot conceive even on fertile days. The contradiction of situations is explained by the individual characteristics of the body of different partners. The probability of conception is determined by the following indicators:

1. regularity menstrual period and timing of ovulation
2. stability of the hormonal background of the female body;
3. male sperm viability;
4. the state of the pelvic organs of a woman;
5. the age of both partners;
6. male sexual activity.

Women with a stable short cycle, in which the duration of the first phase does not exceed one week, are highly likely to become pregnant after menstruation. In patients with a long period between bleedings, conception can take place with spontaneous ovulation caused by endogenous and exogenous causes.

Factors that affect the timing of ovulation

So, pregnancy can occur immediately after menstruation. Conception will take place if early ovulation. Internal and external processes can affect the timing of the rupture of the dominant follicle and the release of the egg:

• infectious or inflammatory diseases reproductive organs;
• cold;
• climate change;
• diet;
• psycho-emotional instability;
• violent emotions (stress or positive experiences);
• taking medications;
• age-related changes;
• bad habits;
• sudden change in body weight.

Getting pregnant after menstruation will work if the bleeding is too long. This condition is called menorrhagia and requires treatment. The peak of fertility in a woman with an average cycle length occurs on the 14th day. If the bleeding lasted 9 days, then sex on the 10th day will lead to the fusion of germ cells.

Pregnancy after menstruation is possible with double ovulation. Emotional experiences can provoke it.

If the girl has an early release of the egg, and then a timely one, then sexual contact after the end of the discharge with high probability will end in fertilization.

Chances of conception on the first day after menstruation

It is believed that it is impossible to get pregnant on the first day after the completion of bleeding. This position is reinforced by the absolute certainty that sex cell not yet mature in the ovary. But not everything is so clear.

You can get pregnant 1 day after the end of menstrual bleeding. The chances increase the next day and increase until the very moment of ovulation. You can get pregnant after your period if:

• the man has good sperm activity;
• early or spontaneous ovulation in a woman;
• prolonged bleeding in a woman (7 or more days);
• spotting that is not associated with rejection of the functional layer of the uterus (when a woman confused them with menstruation);
• hormonal disbalance.

The chances of conceiving on the first day after the completion of the regulation are low, but they are (up to 6%). It is impossible to categorically reject the possibility of fertilization during this period. It is especially dangerous to rely on a lucky chance for partners who do not plan to have children in the near future.

On the second day

The probability of getting pregnant 2 days after the end of the discharge is higher than on the first day. Women with an average duration of the lunar period (as the monthly cycle is sometimes called) may well become a mother after sexual intercourse during this period of time. Knowing estimated time preservation of sperm activity and the duration of the menstrual cycle, the probability of fertilization can be calculated.

If we take as a basis the work of the body of an average woman, then she will ovulate on the 13-15th day. Bleeding takes 5 to 7 days. If on the 7th-9th day sexual intercourse, That male gametes will be able to remain active until 11-14 days. It is easy to guess that on the second day after menstruation it is possible to become pregnant and the probability of fertilization is quite high.

A long period lasting at least 34 days makes it possible to practically exclude the possibility of conception.

On the third or fourth day

The risk of unplanned conception on the 3rd day after menstruation is even higher. The fourth day can at all provide a guarantee of conception of about 30%. Bleeding usually lasts 7 days, and sperm are active for a week after sex. This allows us to say that there is a high probability of fertilization on the 3-4th day after the end of menstruation for patients with any length of the lunar period:

• at short ovulation occurs on the 7-9th day;
• with an average dominant follicle ruptures on the 13-15th day;
• with a long peak fertility occurs at 19-21 days.

The percentage indicator that determines the possibility of becoming pregnant after menstruation for 3-4 days decreases with an increase in the duration of the menstrual cycle.

When the probability of conception is highest

Trying to get pregnant after menstruation is recommended for women with a short lunar cycle. High chances will be for those representatives of the weaker sex, in whom the time from one to the other bleeding does not exceed 21-23 days. It is important that these periods are regular.

The faster the cyclic changes occur, the sooner planning should begin. Women with long cycles it is recommended to try to get pregnant only after a week, and sometimes later. Due to the fact that the length of the follicular period varies, and the luteal phase always has approximately the same duration, it is easy to calculate fertile days from the onset of menstruation.

Pregnancy is likely	Short cycle (21-23 days)	Average cycle (26-28 days)	Long cycle (33-35 days)
33%	7-9	13-15	19-21
31%	6-8	12-14	18-20
27%	5-7	11-13	17-19
16%	4-6	10-12	16-18
14%	3-5	9-11	15-17

Is the calendar method of contraception effective?

As calculations and obstetric practice show, the possibility of getting pregnant after menstruation cannot be ruled out. Under certain life circumstances, ovulation occurs at those moments when a woman least expects it. It is good if the partners plan to conceive. However, some couples, on the contrary, are interested in the possibility of pregnancy for the purpose of protection.

The calendar method for determining safe days is often used by partners. Some women with regular cycle can calculate safe periods and successfully apply this method contraception for many years. However, it cannot be called highly effective. Moreover, experts strongly do not recommend preventing conception by determining infertile days. Statistics show that this technique sooner or later fails.

Modern medicine offers more effective, safer and more available ways contraception: condoms, oral contraceptives, intrauterine systems, patches, vaginal suppositories and others. To choose the most suitable, you should consult with a gynecologist.
