How to calculate safe cycle days?

Despite the fact that today there are many different ways to protect against the onset of unwanted pregnancy, not all women resort to their help. Some avoid buying contraceptives for financial reasons, others can not choose a method that would suit their couple, and someone has an irregular sexual life, so constantly swallow tablets or put a spiral inappropriate.

Virtually all women have heard of such a phenomenon as safe cycle days , in which it is impossible to conceive. But not everyone knows how to count these days. Let's talk about the most popular methods that are used today

But before you begin to explain how to calculate the safe days of a cycle, it is worthwhile to warn that the effectiveness of these methods is extremely low. To resort to this method of protection can be advised only to those women who have a stable menstrual cycle. That is, you can recommend this method of contraception to women aged 25-35 years who are not prone to catarrhal diseases, who do not have stresses, who are not on frequent business trips. In short, the percentage of women who can use the method, oriented to safe days of the menstrual cycle, is very small. You can advise him only to couples who, in principle, are not against the birth of a baby, but have not yet started active planning.

Safe cycle days can be calculated based on the Ogin-Klauss method. The main position of this method is that ovulation in women is, as a rule, in the middle of the cycle. That is, if the break between the monthly is 28 days, then the egg ripens on day 13-14. The egg itself remains viable for two days, but spermatozoa can remain in the "working" state for about three days. Therefore, to calculate the safe days of the cycle, by the time the egg should leave is added four days before and after the expected date. That is, with an ideal cycle, the risk of getting pregnant exists between the ninth and the eighteenth day. Other days are considered safe.

The effectiveness of this method is only 30%, since only a small number of women never fail in the cycle. The shift in the time of ovulation can provoke stress, a cold and many other very diverse causes.

There are other methods to control the female cycle. Safe days can be calculated based on the analysis of vaginal discharge. During the release of the egg, the leucorrhoea becomes more fluid, and upon completion of the ovulation process, it coagulates. It is believed that after three days after the discharge became more dense, it is no longer possible to become pregnant. However, not every woman is capable of qualitatively assessing the nature of her secretions. In addition, various diseases (for example, colpitis) lubricate the picture, making this method completely useless.

One of the most accurate, but rather complex ways to control the female cycle is to measure the so-called basal temperature. This parameter should be measured daily, starting from the first day of the cycle, and the measurement time should be at least 5 minutes. It is necessary to put the thermometer in the morning, before the woman rose from the bed, it is important that the woman slept for at least six hours before the measurement. Sexual contact that occurred the day before or in the morning, nullifies the informativeness of the measurements. Also reduces the effectiveness of the method of taking alcohol and certain medications.

To find out when the safe days are, it's necessary to build a temperature chart. Before ovulation the temperature, as a rule, keeps within the limits of 36,4-36,5 degrees. At a dangerous time, the indicators are sharply reduced, and in the second half of the cycle they become higher (about 37 degrees). In order to make more or less reliable conclusions, it is necessary to accurately measure the temperature for at least three cycles.

Dangerous is the day of ovulation (the temperature dropped sharply) and another two to three days after it. In all other days the probability of pregnancy is low.
