How many days can I get pregnant after menstruation? How quickly can you get pregnant after menstruation? Chance to get pregnant after menstruation

Pregnancy is a long-awaited and happy time for most women. Having come to a common decision to have a child, many couples expect that conception will happen very soon. However, sometimes you have to wait several months, and often much longer. If both potential parents are healthy, then pregnancy most often does not occur due to improper planning of the time of conception. It is possible strictly at a certain moment. Is it possible to get pregnant after menstruation? Or does conception occur before they occur? To answer these questions, you need to figure out how a new life begins to appear in a woman's body.

Egg development

When can I get pregnant after menstruation? On the first day, if the egg has already matured by this time. Even during their intrauterine life, each female fetus begins to form ovaries containing several thousand eggs. They are located in small formations - follicles. Eggs during this period are immature. The girl is born, grows and reaches puberty. From this moment, the regular maturation of eggs begins, which, after fertilization with spermatozoa, will give rise to a new life. This process is regulated by the pituitary gland by increasing the concentration of certain hormones in a woman's blood at the time of egg maturation.

The follicle located on the surface of the ovary begins to grow, acquires signs of cystic formation up to 20 mm in size. An egg cell matures inside it under the influence of hormones. At the same time, the growth of the follicle causes an increase in the concentration of the hormone estrogen in the blood of the expectant mother. Under its action, the growth of other ovarian follicles stops. The maturation of the egg is accompanied by a change in the endometrium - the inner layer of the uterus. During the previous menstruation, it almost completely disappeared, and a favorable environment is needed for the development of the fetus from a fertilized egg. Therefore, the endometrium is updated.

Ovulation

How many days can I get pregnant after menstruation? It depends on the moment of ovulation. This is the process of disintegration of the follicle and the release of the egg that has matured in it. It is ovulation that is the defining moment in the process of pregnancy. The egg moves through the fallopian tube, heading to the uterus. If during this period she meets with a viable sperm, then her fertilization occurs. At the same time, a yellow body appears in place of the follicle that burst during the release of the egg. If conception occurs, it will produce the hormone progesterone, which ensures the normal course of pregnancy. Ovulation occurs most often 14 days before the onset of menstruation. If a woman's cycle is stable and has 28 days, the egg matures in its middle. This allows you to determine exactly the period when the conception of a child is most likely. If the menstrual cycle is less than or exceeds 28 days, then the duration of its first phase changes. The next phase (the time after the release of the egg and before the onset of menstruation) is also about 14 days (12-16).

Symptoms of ovulation

Some women at the time of ovulation feel pulling or cutting pains from the side where the ovary is located, on the surface of which the egg has matured. It is believed that this is due to damage to the mucous membrane of its surface. Such pains are usually short-lived, only in a small number of women they last more than a day and cause significant inconvenience. If this situation repeats during the next cycle, it is better to consult a doctor. He will determine the cause of the malaise and prescribe appropriate treatment if necessary.

Ways to determine the moment of ovulation

What is the probability of getting pregnant after menstruation? Determining the time of ovulation will help you find out. Since this procedure is the first step to the long-awaited conception, you can use several special methods. They allow you to find out quite accurately when the egg will come out. There are two most popular ways.

1. Basal temperature

Determination of basal temperature is its measurement in the rectum. It is better to produce it with a conventional mercury thermometer, since the electronic device can give significant errors. The measurement is carried out in the morning, at the same time every day. It is best to conduct it directly after sleep, while in bed.

In the first half of the menstrual cycle, the same temperature is observed every day - about 37 degrees. Then, a day before the onset of ovulation, it decreases slightly, then there is a jump of 0.5 degrees. This means that an egg has been released. If the thermometer readings do not change throughout the cycle, most likely, ovulation did not happen.

It is worth remembering that such a method cannot be completely reliable. Basal temperature can be affected by a woman's intake of alcoholic beverages, smoking immediately before the measurement, or sexual intercourse shortly before the procedure. Stress or an infectious disease also distorts the indicators.

In order to most accurately predict the onset of ovulation and find out how to get pregnant quickly after menstruation, it is worth measuring the temperature in the rectum for 3 months. At the same time, you need to make a schedule. If there are any factors affecting the measurement result, such as a cold, they should also be noted. Based on the results of all measurements, it will be possible to assume on which day of the next cycle ovulation will occur.

2. Determination of ovulation day using specially designed tests

With this method, it is easy to find out how many days it is possible to get pregnant after menstruation. These tests can be easily purchased not only in a pharmacy, but also in many stores selling a variety of goods. The effect of these tests is based on determining the concentration in the urine of the hormone that synthesizes the yellow body. If, after the measurement, the test showed one band, then there is still a lot of time left before ovulation. If there are two bands, then ovulation is already close. The moment of its onset is determined by the intensity of the color of the second strip that appeared. As soon as its color matches the shade of the control one, the moment of egg release has come. This method is quite accurate, however, you need to purchase more than one test. Measurements are recommended to begin 6 days before the expected date of ovulation. So the girl is able to find out when you can get pregnant after menstruation.

The structure of spermatozoa

Spermatozoa, unlike eggs, are constantly updated in the body of a man. They are formed in the testicles constantly, not cyclically. As a result of the ejaculation process, millions of sperm enter the external environment.

A sperm is a single-celled organism that carries a certain set of genes. There are three components in its structure.

1. The head. It contains genetic material – 23 chromosomes. The head also contains a special component capable of dissolving the egg wall in order to penetrate into the cell.
2. Neck. This is the link between the head of the sperm and its tail.
3. Tail. This part of the sperm plays an important role - it ensures its mobility. The tail contains mitochondria, which release energy and allow the sperm to move.

Sperm viability

The viability of spermatozoa and, accordingly, their ability to fertilize an egg are determined by the well-coordinated functioning of the male genital organs of secretory function. Sperm must have a certain composition of organic substances that are dissolved in it, the necessary acidity and viscosity. If all indicators are normal, then spermatozoa are able to move quickly, remain in the fallopian tube for the required amount of time, and after fertilization lead to the appearance of a healthy fetus.

Fertilization process

Spermatozoa, once in the vagina, begin their upward trajectory into the fallopian tubes. It is there that they can meet an egg moving towards them. There is an opinion that the sperm that first approaches her fertilizes her. Most often this is not the case. Spermatozoa are viable for 24-72 hours after the fact of ejaculation. To fertilize an egg, you need not only to get to it (it takes a long time), but also to penetrate into its inner layer. This happens by splitting the egg wall with a special substance located in the head. So those spermatozoa that get to it at the moment of splitting of the last layer of the wall have more chances to fertilize the egg.

After the sperm enters the egg, their genetic material connects, then its cells begin to divide rapidly. A zygote is formed. Cell division occurs when a fertilized egg moves through the fallopian tube to the uterine cavity. There, the zygote is introduced into the endometrium, which, during the maturation of the egg, acquires a structure favorable for the development of the embryo. Hormonal changes accompanying this whole process prevent the onset of the next menstruation.

Factors influencing the occurrence of conception

Various factors can affect the possible fertilization of an egg. Under their influence, conception can occur at the most unpredictable moment, when by all calculations it should not occur. And, on the contrary, even the most accurate calculation of ovulation time may not give a positive result and may not lead to the onset of a long-awaited pregnancy. When planning the conception of a child, it is necessary to take into account the following features.

1. The normal life span of a sperm is from one to three days. However, sometimes it happens that they can persist for a week. In medical practice, even cases of fertilization of an egg have been recorded a couple of weeks after the fact of sexual contact. You can also get pregnant immediately after menstruation. Of course, this is rare, but when planning a pregnancy, it is worth remembering about the peculiarities of the human body.
2. In rare cases, two eggs can mature during the same menstrual cycle. They come out of the ovary at different times. A woman can determine by calculation the ovulation of one egg, but do not assume that the second one is already maturing. So there is a high probability of getting pregnant after menstruation.
3. The menstrual cycle, even in healthy young women, in whom it has been established for a long time and every month passes clearly on schedule, may in some cases shift. The reason for this may be stress, significant physical exertion, and past illnesses. In older women, failures in the ovulation schedule may occur due to hormonal changes in the body. For example, after the end of menstruation, you can get pregnant quite often, although at this time a woman does not assume the onset of ovulation.

Pregnancy and menstruation

It is believed that pregnancy cannot occur before, during or immediately after menstruation. Most often, this is true. However, the characteristics of the female body, external factors, as well as the viability of spermatozoa can make conception possible even during this period. So how many days can you get pregnant after menstruation?

Pregnancy occurs less often in the first days from the beginning of menstruation. At this time, a particularly unfavorable environment for the life of spermatozoa is created. Even if an untimely ovulation occurred due to the cycle shift, they are unlikely to be able to fertilize an egg and will quickly die.

The time before the beginning of menstruation, at their completion, as well as immediately after the end cannot be considered completely impossible for conception. A failure in the ovulation schedule, the release of two eggs during the cycle at once, as well as spermatozoa that persist for a long time can lead to fertilization. As you can see, you can get pregnant immediately after menstruation. We need to be ready for anything.

Pregnancy planning by calculating ovulation time

How many days can I get pregnant after menstruation? The calculation of ovulation time can greatly help those women who want to get pregnant as soon as possible. Determining the moment of egg release not only makes fertilization possible, but also allows the expectant mother to assume the onset of pregnancy. A woman is more attentive to her health, trying not to allow any actions that may harm the health of the unborn baby.

Can a girl get pregnant after menstruation? Let's try to figure it out. If a woman is healthy, has regular periods and is not under stress, it can be assumed that ovulation will occur on the 14th day with a cycle consisting of 28 days, and on the 16th with a 30-day cycle. Since spermatozoa can persist for about three days, and an egg for up to 48 hours, sexual contact can most likely lead to conception about three days before and after ovulation. This time starts from the 11th day of the cycle and reaches the 16th day. So, you can get pregnant a week after your period.

When choosing a method of contraception, you should not completely rely on a calendar method based on determining the time of ovulation. After all, it is possible to get pregnant after menstruation, before they begin and even at the end of menstruation. It is better to consult with a gynecologist who will choose more reliable means of contraception.
