How many days can I get pregnant after menstruation? How fast can I get pregnant after menstruation? Chance to become pregnant after menstruation

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

Development of the egg

When can I get pregnant after a period? The first day, if by this time the egg has already matured. Even during their prenatal life, each female fetus begins to form ovaries, which contain several thousand eggs. They are located in small formations - follicles. Eggs during this period are unripened. The girl appears in the light, grows and reaches sexual maturity. From this moment regular egg ripening 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 in the blood of a woman of certain hormones at the time of maturation of the egg.

The follicle located on the surface of the ovary begins to grow, acquires the signs of cystic formation up to 20 mm in size. Inside it ripens under the action of hormones egg. At the same time, the growth of the follicle causes an increase in the blood of the expectant mother in the concentration of the hormone estrogen. Under its action, growth of other ovarian follicles stops. 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 for the development of the fetus from a fertilized egg, a favorable environment is needed. Therefore, the endometrium is updated.

Ovulation

How many days can I get pregnant after menstruation? It depends on the time of onset of ovulation. This is the process of decay of the follicle and the release of the matured egg in it. It is ovulation is the defining moment in the process of pregnancy. The egg moves along the fallopian tube, heading towards the uterus. If during this period she meets with a viable sperm, her fertilization takes place. At the same time, on the place of the follicle that burst during the release of the egg, a yellow body appears. If conception occurs, it will produce a progesterone hormone that provides a normal course of pregnancy. Ovulation occurs most often 14 days before the onset of menstruation. If a woman's cycle is stable and lasts for 28 days, the egg ripens in its middle. This allows you to determine exactly the period when the conception of the 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 (time after egg release and before the onset of menstruation) is also about 14 days (12-16).

Symptoms of ovulation

Some women at the time of onset of ovulation feel drawing 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 considerable inconvenience. If this situation recurs and during the next cycle, it is better to see a doctor. He will determine the cause of the ailment and appoint appropriate treatment if necessary.

Methods for determining the moment of ovulation

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

1. Basal temperature

Determination of basal temperature - measurement of it in the area of the rectum. It is better to produce it by a conventional mercury thermometer, since the electronic device can give significant errors. The measurement is carried out in the morning, at the same time daily. It is best to spend it directly after sleeping 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 drops a little, then there is a jump of 0.5 degrees. This means that the egg has been released. If the thermometer readings do not change throughout the cycle, most likely, ovulation has not occurred.

It is worth remembering that such a method can not be completely reliable. The basal temperature can be influenced by the intake of alcohol by a woman, smoking immediately before the measurement, or sexual intercourse shortly before the procedure. Stress or an infectious disease also distorts the indicators.

To accurately predict the onset of ovulation and find out how quickly to get pregnant after menstruation, it is worthwhile to measure in the rectum of the temperature for 3 months. Thus it is necessary to make the schedule. If there are any factors influencing the result of measurements, for example, a cold, they should also be noted. By results of all measurements it will be possible to assume, in what day of the next cycle ovulation will come.

2. Determination of the day of ovulation with specially developed tests

With the help of this method it is easy to find out, after how many days it is possible to get pregnant after menstruation. These tests can be easily purchased not only in the pharmacy, but also in many stores selling a variety of products. The effect of these tests is based on the determination of the concentration in the urine of the hormone that synthesizes the yellow body. If after the measurement the test showed one band, then until the onset of ovulation there is still a lot of time. 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 emerging second band. As soon as its color coincides with the shade of the control - the moment of the egg's release has come. This method is quite accurate, however, the test should not be purchased alone. It is recommended to start measuring the days 6 before the expected date of ovulation. So the girl is able to find out when to get pregnant after the menstrual period.

Structure of spermatozoa

Spermatozoa, in contrast to eggs, are constantly updated in the body of men. They are formed in the testicles constantly, but not cyclically. As a result of the process of ejaculation, millions of spermatozoa fall into the external environment.

Spermatozoon is a unicellular organism, which carries a certain set of genes. In its structure, three components are distinguished.

1. Head. In it is concentrated the genetic material - 23 chromosomes. The head also contains a special component capable of dissolving the wall of the egg to penetrate inside 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 secrete energy and allow the sperm to move.

Viability of spermatozoa

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

The process of fertilization

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

After the sperm enters the egg, their genetic material is connected, then its cells begin to quickly divide. A zygote forms. Cell division occurs at a time when a fertilized egg moves through the uterine tube to the uterine cavity. There the zygote is implanted in the endometrium, which during the maturation of the egg acquires a structure favorable for the development of the embryo. The hormonal changes that accompany the whole process prevent the next menstruation from coming.

Factors affecting the onset of conception

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

1. The usual 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 the egg were recorded a couple of weeks after the fact of sexual intercourse. You can also get pregnant right after the menstrual period. Of course, this is a rarity, but when planning a pregnancy, it is worth remembering the characteristics of the human body.
2. In the rare case, two eggs can ripen for 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 ripens. So there is a high probability of getting pregnant after menstruation.
3. Menstrual cycle even in healthy young women, from whom it has long been established and every month passes clearly on schedule, can in some cases shift. The cause of this can be stress, significant physical exertion, and transferred diseases. In older women, glitches 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 the woman does not expect the onset of ovulation.

Pregnancy and menstruation

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

Less often, pregnancy occurs in the first days from the beginning of menstruation. At this time a particularly unfavorable environment is created for the life of spermatozoa. Even if in connection with the shift of the cycle there was an untimely ovulation, they are unlikely to be able to fertilize the ovum and will quickly die.

The time before menstruation, when they are completed, and also immediately after the end, can not be considered completely impossible for conception. Failure in the schedule of ovulation, the exit during the cycle of two eggs at once, as well as long-remaining spermatozoa can lead to fertilization. As you can see, you can get pregnant right after the menstrual period. We need to be ready for anything.

Planning pregnancy by calculating the time of ovulation

How many days can I get pregnant after menstruation? Calculating the time of ovulation is very helpful for those women who are trying to get pregnant as soon as possible. Determining the moment of release of the egg not only makes it possible for fertilization, but also allows the expectant mother to presume pregnancy. A woman takes a closer look at her health, trying not to allow any actions that could damage the health of the baby's future.

Can a girl get pregnant after a period? Let's try to understand. If the woman is healthy, has a regular period and is not in a state of stress, it can be assumed that ovulation will occur on her on the 14th day with a cycle of 28 days and on the 16th with a 30-day cycle. Since spermatozoa can persist for about three days and the egg can last up to 48 hours, it is most likely that a sexual contact can occur about three days before and after ovulation. This time starts from the 11th day of the cycle and comes to the 16th day. So, you can get pregnant a week after the menstrual period.

When choosing a method of contraception, do not rely entirely on the calendar method, based on the timing of ovulation. After all, it is possible to get pregnant after menstruation, before their onset and even at the end of menstruation. It is better to consult a gynecologist who will choose more reliable contraceptives.
