Fertile days - what is it?

For each female body is characterized by a monthly offensive of such days, when he is most ready for conception. In medicine, they are usually called fertile. A special need to determine the period of their onset occurs during pregnancy planning, or, on the contrary, when a woman does not want to have children yet. Let's take a closer look at this concept.

When does the period of fertility in the menstrual cycle come?

Having dealt with what it is - fertile days of the cycle for women, and what this term means, we will try to establish when they come and on what the duration of this period depends.

As you know, the menstrual cycle takes its record from the first day of bloody discharge. At their end, after about 5-10 days in the body of a woman there is an ovulatory process - the release of a new, matured, ready for fertilization of the egg in the abdominal cavity. This is observed approximately in the middle of the menstrual cycle itself. It is this time is auspicious for conception. However, it must be taken into account that the fertility window begins much earlier.

The thing is that male sex cells have a long-term readiness for fertilization. It is established that, after hitting the genital tract of a woman, spermatozoa can keep their mobility there for 3-5 days. That is why, in order to establish the duration of fertile days in a cycle, it is necessary to take 5 days from the date of ovulation.

How correctly to calculate the beginning and the end of fertile days?

Despite the fact that some women have an idea of ​​what fertile days are in the women's calendar, they do not always know how to correctly establish their beginning and end. This fact is explained by the fact that, at times, a girl has no idea when she has ovulation in her body.

In order to establish this fact, it is enough to keep a diary in which it is necessary to note the values ​​of basal temperature. Where there will be an increase in its values, and there will be ovulation. For greater reliability it is necessary to carry out similar measurements during 2-3 menstrual cycles, tk. quite often ovulation can occur a little earlier or, conversely, a little later.

More precisely, it is possible to establish the period of ovulation in a cycle of special medical tests that outwardly resemble those used for rapid diagnosis of pregnancy. So, following the instructions attached to them, the woman herself, with a high degree of probability will be able to establish the time of beginning in her body in ovulation.

What other way exists for determining fertile days in a cycle?

The method of Billings - allows you to set the time of ovulation in the body of a woman by the consistency of the cervical mucus. Such a study takes quite a long time and takes about 6-9 months.

During this time, a woman should keep a diary in which to indicate the consistency, color and amount of cervical mucus on this or that day of the cycle. As you know, after the end of the month, any allocation is completely absent ("dry days"). Then there are minor mucous discharge. Closer to ovulation, they become more viscous, increase in volume. In appearance, resemble raw egg white hen. Given this fact, the woman marks the day in the chart when they appeared - it is he who will point to ovulation.

Thus, it must be said that every woman, knowing what the concept of "fertile days" means, why and how to calculate them, can easily plan pregnancy or prevent her offensive, avoiding sexual relations during this period of the cycle.
