Is it possible to get pregnant if the cycle is 21 days. What days of the cycle can you get pregnant: when the body and the egg are ready to conceive a child and how to calculate the probable time of conception. Favorable and unfavorable days for conception

When trying to conceive a baby, the question often arises, how to get pregnant after menstruation quickly? To answer, you need to understand the physiological processes female body. The menstrual cycle is divided into three stages - follicular, ovulatory and luteal, each in time proceeds in accordance with individual parameters. The main calendar method for calculating an auspicious day is the main one, in which the date of ovulation is determined.

Stages of the menstrual cycle

At the first stage of the menstrual cycle, a follicle is formed, from which the egg subsequently matures. After that, ovulation or “fertile window” occurs from 1.5 to 3 days, when the probability of conception is the highest. If the egg is fertilized, then the body is rebuilt at the hormonal level in order to maintain pregnancy. The absence of a male spermatozoon leads to the reverse process, a natural process occurs - uterine bleeding.

The likelihood of conception after the ovulation period is getting smaller every day. If a woman's regular menstrual cycle is 28 days, then the fertile window is formed between the 13th and 15th day. In the next few days, the chances decrease to 10% and further, the figure is about 2-5%.

When is the best time to get pregnant before or after your period?

When a man and a woman choose the best time for conception, it is necessary to focus on the ovulation period and use the calendar method of calculation. If menstruation is irregular, and it is not possible to calculate the fertile window, then when planning a pregnancy, it is recommended that both partners undergo a complete examination in order to exclude or identify possible diseases that affect the bearing of the fetus.

When answering the question, when is it better to get pregnant before or after menstruation, you should focus on regularity, so the correct answer will be - 7-10 days after the start.

Best days to conceive after period

When days are determined, they are guided by the number of days and the regularity of the cycle. Favorable days come exactly in the middle, at this moment the egg is ready for fertilization.

It cannot be guaranteed that pregnancy will not occur immediately after the end of menstruation, the probability of conception is small, but it exists, especially with irregular periods and the inability to calculate the time of ovulation. In such a situation, you can use ultrasound, which will most accurately determine the required day.

When calculating the date, the following factors are taken into account:

  • short duration - less than 21 days, due to conception in the next day by the end of menstruation;
  • prolonged menstruation indicates the possibility of fertilization closer to the beginning;
  • irregularity - indicates the impossibility of calculating the day of ovulation;
  • additional bleeding can be confused with menstruation, which will allow you to miss a prosperous day due to the impossibility of calculating;
  • ovulation of 2 eggs, a rare occurrence, hereditary.
During the lactation period, when the pregnancy with the first child has successfully ended, the chance of re-conceive is quite small. I associate the situation with the hormonal background of a woman. At breastfeeding prolactin is intensively produced, which prevents the production of estrogen, the hormone responsible for the cyclical capabilities of the female body. The probability of becoming pregnant with a second child increases significantly with a decrease in lactation, as soon as the baby is introduced to additional food, complementary foods, in addition to breast milk.

In adolescence, menstruation has not yet been properly established, the risk of conception in the absence of bleeding increases significantly. On this age stage should be attentive not only to the calculations, but also to the methods of contraception.

When can I get pregnant after menstruation - calculator

When choosing a method of counting, you should evaluate the regularity of menstruation, if there is no constancy, you will have to use additional methods to determine ovulation. To date, there are special tests that determine the appropriate days. You can keep a basal diary, where you want to record the rectal temperature, as it will differ during ovulation.

Stressful situations, bad habits, taking certain medicines, unreasonable and uncontrolled diets with a sharp decrease in weight disrupt the hormonal balance, which leads to failures, the maturation of the egg will occur earlier or later than the due date.

To calculate favorable days, you need to understand that the first day of the onset of bleeding leads the countdown. In the next month, the date is shifted by 2-3 days and the first day is considered the final one in the cycle. Thus, in the absence of disruptions in the hormonal background, it becomes not difficult to calculate when you can get pregnant after menstruation. The calculator for calculating the most suitable day will help determine the successful date for the conception of a baby.

How often do women ask themselves the question? Is it possible to get pregnant that day? In order to accurately verify the result, you need to visit a gynecologist. The doctor can conduct a series of studies and determine whether conception has occurred. This article will consider the 20th day of the cycle. You will find out if pregnancy is possible at this time. Also get acquainted with some of the opinions of doctors and patient reviews.

Note that the material presented is not a guarantee that in your case everything will be exactly the same. The body of each woman is individual and full of its own characteristics.

A few words about the theory: the process of fertilization

To understand whether conception is possible on the 20th day of the cycle, you need to learn about the principle of this process. For the onset of pregnancy, two cells are needed - male and female. Spermatozoa are released during ejaculation at any time. A woman's body is a little different. The representative of the weaker sex washes to conceive a baby not every day of the cycle. There are so-called

Doctors divide women's periods into short, average and long. In the first case, the cycle lasts up to three weeks. The last one is 35 days. All this is considered normal and does not require medical intervention. Consider the separately described cycles and find out if conception is possible on the 20th day of the cycle.

The average woman with regular periods

With a period of 28 days, the egg is released approximately on the 14th-16th day of the cycle. The viability of the gamete is only a few hours. If sexual intercourse occurs on the 20th day, then pregnancy is extremely unlikely. This fact is explained by the fact that more than 4 days have passed since ovulation.

Despite the available data, conception can still occur. Remember that every representative of the weaker sex has hormonal disruptions that shift ovulation in one direction or another. Also, sometimes two eggs can be released in a cycle. This is more the exception than the rule. However, it should always be remembered.

in a short cycle

Is it possible to get pregnant on the 20th day of the cycle in this case? The answer to this question will be more negative than doubtful or positive. For women with a short cycle, it lasts up to three weeks and is 21 days. Ovulation occurs about a week after a new period. Therefore, if sexual intercourse without protection occurs on the 20th day, then the next cycle will already begin on the 21st. The gamete will simply die by the specified time.

It is worth considering another situation. As you already know, the rupture of the follicle occurs approximately on the 7th day after menstruation. The viability of spermatozoa in the genitals of a woman is up to ten days under favorable conditions. Based on this, it can be assumed that the contact took place on the 20th day, and ovulation occurred 8 days later. Pregnancy may well come from a gamete, which will still wait in the wings. However, you will learn about your new position in the next cycle.

A woman with a long cycle and the likelihood of conception

On what day of the cycle does ovulation occur in the fairer sex with a period of 35 days? In this situation, the rupture of the follicle occurs around the 21st day. Can pregnancy occur with sexual intercourse a few hours before? Certainly yes.

Doctors say that this particular day is the most favorable for conception in the fairer sex with a long cycle. That is why, if you are not planning a pregnancy, you should be especially careful during intercourse. Use barrier methods of contraception.

Ovulation symptoms every woman needs to know about

On what day of the cycle ovulation in certain women, you already know. It is also worth learning to determine the output of the gamete by symptoms. This will allow you to most accurately answer the important question: is pregnancy possible?

  • Allocations on the 20th day of the cycle during ovulation are usually mucous, viscous and transparent. It is this environment that is most favorable for spermatozoa. In it, the cells move quickly, reaching their goal.
  • You can determine the onset of ovulation using special means(testing, laboratory research, ultrasound monitoring).
  • The position of the cervix. This symptom will be indicative only with long-term regular examination. becomes softer, opens up a little and rises up. Remember that the study should be carried out exclusively with clean hands with short-cut nails.
  • Increased libido. With ovulation on the 20th day of the cycle, as in any other, there is an increase in sexual desire.

is pregnancy possible?

The first day of the cycle is the day on which the bleeding began. Doctors say that normally every woman has up to two anovulatory cycles per year. What it is? Can pregnancy occur on the 20th day in this case?

An anovulatory cycle is a period when the ovaries are dormant (not functioning). Ovulation does not occur this month. Therefore, pregnancy can absolutely be ruled out. It is worth noting that anovulatory cycles are often longer or shorter than normal periods. You should not focus on this if the absence of menstruation lasts up to 40 days.

Definition of pregnancy on the 20th day

What are the signs of ovulation on the 20th day of the cycle, you already know. Often women have a question: is it possible to establish the presence of pregnancy at this time? It is almost impossible to determine this fact on your own. The most popular diagnostic tool is a test. However, on the 20th day, it will show you a negative result due to the fact that there is still a low level in the urine. chorionic gonadotropin.

It is possible to establish the fact of conception on the 20th day with the help of laboratory tests. However, they will show an accurate picture only with early ovulation. In other words, if the egg was released on the 7th day, then it is likely to see a positive level of chorionic gonadotropin. Progesterone (cycle day 20) will also be high, corresponding to the first trimester.

Ultrasound examination at this time will not yet give a clear picture. Even with the onset of pregnancy, the fetal egg is still negligible, it is simply impossible to see it.

Many couples who refuse contraception think they will get pregnant right away. In fact, the preparation of the body, especially the body of a woman, for conception is a cycle. You are most likely to get pregnant only on certain days of your cycle. At the same time, it is necessary to comply with such conditions as the refusal of contraception and the complete reproductive health of a woman and a man who have sexual intercourse.

What days of the cycle can you get pregnant

To understand which days of the cycle are ideal for conceiving a child, it is important to understand the work of the female reproductive system. On the first day of menstruation, follicles begin to grow on the ovary. They are sacs in which eggs grow and mature one at a time. After about a week, one of the follicles is determined, which continues to grow. Other follicles freeze in their development.

With a 28-day menstrual cycle, which is counted from the first day of menstruation, on the 14th day the follicle bursts and an egg is released from it. With a 35 day cycle, this happens on the 17th day. The uterine or fallopian tube is the "tunnel" through which the egg moves into the uterine cavity.

It turns out that it is most likely to become pregnant, subject to the other conditions described above, in the middle of the cycle. That is, with a 28-day menstrual cycle, the most likely days of conception are the 14th and 15th days. At 35 days, respectively, these are the 17th and 18th days of the menstrual cycle. Sex on other days is much less likely to result in conception.

There is also a chance of getting pregnant on other days that are in close proximity to the optimal days for conception. This is due to the fact that the egg in the body of a woman lives from 24 to 48 hours. It is also necessary to take into account that after the completion of sexual intercourse, spermatozoa can remain active in a woman's body for up to 7, in some cases even up to ten days.

Every pregnant woman looks forward to seeing her baby. Thanks to widespread use, it has become much easier for women to fulfill such a desire.

Why is it possible to get pregnant during ovulation

It is after ovulation that the egg begins its journey through the fallopian tube to the uterus. It is in the fallopian tube that conception most often occurs. Spermatozoa move first into the cervical canal, then into its cavity, and then into the tubes.

It's interesting to know! Spermatozoa move at a speed of about 2 mm per hour. It seems like it is very slow, but there are a huge number of obstacles on their way. Most spermatozoa die without passing through the acidic environment of the vagina, which is detrimental to them. Then a small part passes through the mucus of the cervical canal and the uterine cavity. Only a few reach the tube where the egg is located after ovulation.

The life span of an egg only in some cases is several days, as a rule, it is only a few hours. That is why the most favorable time for conception is the period of ovulation with some deviations forward or backward.

Note! Since the lifespan of the egg is shorter than that of the sperm, it is preferable to have sex before ovulation than after it. Spermatozoa are more tenacious and in the cavity of the fallopian tube they can wait longer for the egg than it does for them.

How to determine the day of ovulation

Summing up, we can say that the fertile period or the period of the greatest probability of occurrence is the day of ovulation, as well as a few days before and after it. Ovulation occurs every month in the middle of the cycle, but what are the possibilities for determining the exact period of its onset.

Possible methods for determining ovulation:

  • Calendar. Suitable for those women who have a regular cycle. With the calendar method, the day of ovulation is considered the middle, the 14th day of the menstrual cycle before the start of the next menstruation. A method that has been proven over the years, but is unreliable, the probability of error is very high;
  • Measurement of rectal temperature. The method is based on regular measurement of temperature in the rectum. The next day after ovulation, the temperature increases by 0.2-0.4 degrees. The disadvantages of the method include the not very pleasant process of the procedure itself. Also, various side effects can affect the result;
  • Home ovulation test. Can be bought at the pharmacy, a fairly new way of family planning. The accuracy of the test is very high. It shows the level of luteinizing hormone, which is considered a precursor to ovulation. A sharp increase in the hormone suggests that ovulation should occur in the next day;
  • ultrasound. Clinical and precise method. The disadvantages include the fact that he states the fact of ovulation, but does not predict its possibility. The clinic will need to be visited 4-5 days in a row;
  • Analyzes in the antenatal clinic. In the middle of the cycle, you can contact the gynecologist so that he, using the analysis of mucus from the cervix, determines the date of ovulation. The run-up here will be in two or three days. Vaginal mucus just before ovulation becomes thin and transparent. If the mucus is rubbed between the fingers, it will not break immediately;
  • Monitor all symptoms. If you successfully combine the calendar method and the measurement of basal temperature, as well as observe the mucus, then you can determine the period of ovulation with great accuracy;

Is it possible to get pregnant before and after menstruation

The probability of conception during this period is very small. It is believed that 2-3 days before the onset of menstruation and after their end are the most unfavorable days of the cycle for conception. But the body of each woman is individual, so conception is possible at any period of the cycle. Some doctors recommend that couples who want to conceive have sex every other day between the 10th and 18th day of their menstrual cycle.

Four or more intercourse per week is the optimal rhythm for conception. Such a rhythm may appear when a woman becomes pregnant in the period before or after menstruation. Statistics say that the probability of conceiving and becoming pregnant within one menstrual cycle is 20%.

Pregnancy during menstruation

Pregnancy during menstruation is unlikely, but possible. Conception, despite the fact that each of its stages has been studied by science, is a mystery of nature. And from nature you can expect anything. If you explain the possibility of getting pregnant during menstruation scientifically, then the preservation of sperm activity also affects. Also, sometimes the egg can mature before the middle of the cycle or after it.

Note! If you notice a sudden change in the cycle, then be on the lookout. During this period, getting pregnant during menstruation is much more likely.

Most often, during menstruation, girls who have an unstable menstrual cycle become pregnant. In this case, the highest probability of becoming pregnant is in the last days of menstruation, when an unfertilized egg is released from the follicle.

The best days for pregnancy in terms of physiology

This article describes in great detail all the physiology of a woman that you need to know in order to conceive a child. Therefore, in order to get pregnant the first time, it is very important to correctly determine the day of ovulation or egg maturation. To do this, monitor your menstrual cycle and try to use a comprehensive technique.

If conception did not happen the first time, you should not worry. In perfectly healthy women, ovulation occurs eight times out of ten cycles. Do not forget about such concomitant factors as, for example, stopping oral contraception. If the woman is younger than thirty years old, then doctors are advised not to worry about the lack of pregnancy during the first year of trying. With age, the difficulty with conception increases, so after six months of unsuccessful attempts, it is best to consult a doctor.

Don't focus on calculating your ovulation and fertile days by having sex on a schedule. Don't forget to enjoy the process. Let conception be pleasant side effect regular lovemaking with a dear and dear man.

Successful conception requires not only the desire and readiness of two people to become parents, but also the right time for this.

We are not talking about the phase of the moon, retrograde Mercury or the most favorable period of the day. We are talking about the phases of the menstrual cycle. Evgenia Balashova, PhD, obstetrician-gynecologist, endocrinologist, reproductologist at the Gynecology Clinic, tells about this to the readers of Letidor in a simple and accessible language.

Traditionally, women who are interested in this issue can be divided into two groups: those who are protected by the cycle, and those who calculate the most favorable days for conception in order to increase the chances of becoming pregnant.

I want to immediately note the fact that the "peak fertility" in women is 24 years (the frequency of pregnancy per menstrual cycle is 20%).

On the one hand, this is quite a bit (it is worth imagining 80 out of 100 married couples who were upset when they did not see the coveted two stripes on the test). On the other hand, this is a lot for those couples who are protected by the “physiological method”.

Phases of the menstrual cycle

Let me remind you the phases of the menstrual cycle: this is menstruation, which is the starting point, the follicular phase (first), ovulation and the luteal phase (second). Then everything repeats from the beginning.

In fact, the menstrual cycle is different for everyone - it can be short (21 days) and long (35 days). But here the luteal (second phase) of the cycle is more than 10 days, as a rule, does not happen.

Accordingly, the most convenient option to calculate ovulation is to subtract 10-12 days from the average duration of your menstrual cycle.

For example, with a menstrual cycle of 21 days, this is the 9th - 11th day, for a menstrual cycle of 30 days, this is the 18th - 20th day.

What happens in the follicular phase

Let's see why the duration of the follicular phase is so different.

At the beginning of each menstrual cycle (2-3 days), a group of follicles is determined in both ovaries, which are going to grow. These are the so-called antral follicles. Usually, the doctor counts them during an ultrasound scan and draws a conclusion about the woman's follicular reserve.

For some period of time, these follicles "agree among themselves" - which of them will be the leader, and the rest of the "support group" goes into atresia - that is, into regression. From that moment on, no more follicles will grow.

The duration of the follicular phase depends on the duration of these "negotiations".

Sometimes for this group of follicles it is immediately obvious which of them is the leader. Then ovulation can happen in 8-10 days. But sometimes they can't "negotiate" long enough - for example, for 30 or more days. Moreover, such scenarios can be with the same woman!

This is usually influenced by the combination external factors- moon phase, change atmospheric pressure by 15-20 mm Hg, a change in daylight hours - and from internal factors, such as hormonal levels, the presence or absence of functional ovarian cysts in the previous cycle, etc.

Sometimes, for example, during an ultrasound performed on the 9th-11th day of the menstrual cycle, I announce to patients that they are ovulating, which is happening right here and now. And this is in women who tend to have a cycle of 30 - 32 days! But they, as we have already understood, usually ovulate on the 20-22nd day.

This is why contraception is not a reliable method of contraception.

And that is why those women who dream of pregnancy need a regular sex life, and not just on the expected dates of ovulation.

What happens to the leading follicle

After the follicles have agreed, the leading follicle grows with average speed 3 mm in two days to 19 mm in diameter. And after that - at a rate of 3 mm per day up to 27 mm. Then it bursts - this is ovulation. This period takes on average no more than 10-12 days. In place of the bursting follicle, a temporary endocrine gland (yellow body) is formed, which secretes progesterone. This hormone is necessary to maintain the onset of pregnancy.

If pregnancy does not occur, the concentration of progesterone decreases, and menstruation begins.

Sometimes, in the case of "particularly long negotiations" lasting 20-25 days, when the next menstruation should already come, the leading follicle is just maturing and it ruptures. It turns out that ovulation occurred on the days of the expected next menstruation, and the woman is not protected, because she thinks that menstruation will come today or tomorrow.

If the menstrual cycle is irregular

We considered the options for physiological deviations of the normal regular menstrual cycle. If the cycle is irregular (with fluctuations of 7-10 days or more), then such calculations are not relevant at all. What to do?

For women planning a pregnancy, I advise either to conduct ovulation tests or go for folliculometry (ultrasound).

Women who are not planning a pregnancy should choose the optimal and reliable method of contraception together with their doctor.

The fair sex, on the one hand, is easy to get pregnant, but on the other, it is difficult. Why is there such a duality? Let's turn to physiology. A woman of reproductive age ovulates every month around the middle of her cycle. This term refers to the release of a mature egg from the ovary. This process takes only 1-2 days.

Many people, after reading the text written above, will probably think that getting pregnant is very simple - you just need to calculate the day of ovulation, and before and after it, have sex with your partner. However, everything is not as simple as it seems. If it was possible to get pregnant strictly in the middle of the cycle, then there would be no unwanted pregnancies and women who dream of a child, but cannot get pregnant for some reason.

Women who have chosen the calendar method of contraception and refused other means of protection (condoms, various drugs), we are sorry, because there is absolutely no safe days. You can get pregnant at any time. It is only necessary to take into account that on some days the chances of conceiving a baby are great, while on other days they are significantly reduced. There are no periods with zero probability.

A relatively “safe” time can be considered a couple of days before menstruation and a couple of days after them. To calculate "dangerous" days, you need to know the duration of the menstrual cycle. It must be stable - this is the main condition.

With a 28-30-day menstrual cycle, the highest chances of conception occur on the 14-15th day, since ovulation occurs around this time. Deviations are also possible for a number of reasons: due to nervous breakdowns, stress, the presence of diseases, the use of drugs.

How to calculate without errors what days you can get pregnant?

Calculating the days on which you can conceive a child is not so simple. To do this, you need to analyze the entire menstrual cycle, taking data for the last 6-12 months. If hormonal contraceptives were used at that time, the calculation results may be incorrect.

In order not to forget what days menstruation occurs, you should create a special calendar. If the menstrual cycle is not regular, then it will not work to determine which days you can get pregnant. It is best in such cases to use other methods of calculating favorable periods for conception.

If minor deviations are observed during the studied time period, then the following step-by-step calculation can be made:

  1. Select the longest and shortest menstrual cycles for 6-12 months;
  2. Subtract the number 18 from the number of days of a short cycle. The result obtained is the day from which the period with a high probability of becoming pregnant begins. For example, the shortest cycle is 25 days. Subtracting 18, we end up with the number 7. This means that the favorable period for conception begins from the 7th day of the menstrual cycle;
  3. Subtract the number 11 from the number of days of the longest period. The result obtained is the day on which the period with a high probability of becoming pregnant ends. For example, the longest cycle is 29 days. Subtracting 11, we get the number 18. Thus, on the 18th day of the menstrual cycle, the favorable period for conception ends;

From this example, it can be seen that the highest probability of becoming pregnant remains in the period from the 7th to the 18th day.

Table of favorable days for conception:

Is it possible to conceive before menstruation?

An unequivocal answer to this question cannot be given. Conception may or may not occur. First, let's see why the above question can be answered in the negative.

As you know, ovulation occurs in the middle of the cycle. Before the onset of menstruation, the egg dies. If ovulation occurs much later or repeatedly, then an interesting situation may not occur, since the woman's hormonal background will be set to a new cycle.

Now we will explain why conception can occur before menstruation. In healthy women with irregular sexual life the chance of getting pregnant is quite high. Conception can occur after any sexual intercourse.

The body can react to such a rare event with unscheduled ovulation. It can also be provoked by substances contained in semen. Women who regularly have sex with a regular partner may not experience this.

Is it possible to conceive during menstruation?

Pregnancy during the first days of menstruation is unlikely. This is due to an unfavorable environment for spermatozoa and for implantation of the embryo (abundant bleeding). However, "surprises" from nature should not be ruled out.

Conception in an unfavorable period can occur in the following cases:

  • with prolonged menstruation (for example, less than a week may remain before ovulation, and then the sperm will wait for the release of a mature egg);
  • due to menstrual disorders caused by diseases, infections, physical activity, stress;
  • with an incorrect calculation of the period of safe sex (due to the irregularity of the menstrual cycle).

Is it possible to conceive immediately after menstruation?

Many representatives of the fair sex claim that it is impossible to get pregnant within a few days after the end of menstruation. Doctors do not adhere to this point of view. They warn that at any time you can get pregnant.

Spermatozoa entering the female genital tract can remain viable and active for several days. If the menstrual cycle is short and the periods are long, then the chances of getting pregnant will be high. Sexual intercourse can just take place during the most auspicious days for conception.

Pregnancy immediately after menstruation can occur for the following reasons:

  • due to the ability of spermatozoa to maintain their activity for several days;
  • due to the maturation of several eggs in one menstrual cycle;
  • due to the timing of ovulation. It can happen not in the middle of the menstrual cycle, but much earlier or later. The "culprit" of such disorders in young girls is the irregularity of the menstrual cycle, and in adult women - hormonal abnormalities.

Based on this, we can say that the calendar method is not a reliable means of contraception. For some women, it is not suitable at all.

What period is most likely to become pregnant: ways to determine

You can calculate the most favorable days for conception not only using the calendar method. There are several other more efficient ways:

  1. Determination of basal temperature;
  2. Conducting ovulation tests;
  3. folliculometry;
  4. Subjective feelings.

Determination of basal temperature

To calculate the period when the probability of conceiving a child is high, it is necessary to measure the basal temperature in the anus every morning after waking up from the beginning of the menstrual cycle (from the 1st day of menstruation).

Errors can occur for several reasons:

  • due to overwork or illness (during such periods, the temperature is always elevated);
  • if a lot of alcohol was drunk before the measurement;
  • due to taking certain medications;
  • if sexual intercourse occurred 6 hours (or less) before the measurement;
  • due to lack of sleep.

Based on the measured data, a graph should be drawn up, which can be supplemented daily with new results. In the first half of the menstrual cycle, the temperature ranges from 36.6 to 36.9 degrees. It rises above 37 degrees after the release of a mature egg.

You can find out when ovulation occurs if you carefully study the schedule. For 12-16 days basal body temperature may decrease slightly. This will herald the onset of ovulation in the coming hours. That's when you can get pregnant. At this time, women who dream of a baby should have sex.

Conducting ovulation tests

Modern and more accurate means of determining the release of an egg are ovulation tests. They even look like tests with which you can find out about pregnancy. The result is shown as 2 bars. The difference between the tests is only in the reagents. For example, ovulation-determining products contain a substance that reacts to the presence of luteinizing hormone (LH), the level of which in the body rises 23-36 hours before ovulation.

In order not to miss the long-awaited event, you need to do tests every day and at the same time. After ovulation, the LH level drops significantly, and then the strips begin to show a negative result. Manufacturers that produce ovulation tests put several strips in the package. Due to this, this method of determining favorable days for conception is the most justified and convenient.

Folliculometry

Diagnosing the period in which you can get pregnant is very simple. via ultrasound (ultrasound). This method cannot be called economical. It is suitable for those women who want to conceive a child, but they can’t do it.

It is recommended to visit the ultrasound room from the 10th day after the start of the last menstruation. Within a few days, the doctor will evaluate the growth of the dominant follicle in the ovary. When it reaches a size of 18-24 mm in diameter, an egg ready for fertilization will come out of it. The formation of the follicle may not lead to ovulation. It may not break, but regress. Such cases are rare, but they do occur in real life.

The main signs of the onset of a favorable period for conception, which he sees medical worker on the monitor during ultrasound, it is a corpus luteum located in the ovary without a dominant follicle, as well as a little fluid behind the uterus.

The quality of the endometrium affects the onset of pregnancy. It is known that an egg fertilized by a sperm must be implanted in the uterine wall for subsequent development. If by the time of ovulation the endometrium does not reach a certain thickness, then pregnancy will not occur, since the fertilized egg will not be able to attach to the uterus and will die.
