Of course, every girl at least once was interested in the question of which days the fertilization of the egg is impossible and whether there is a risk of getting pregnant during the "critical" days. All of the above is an integral part of such a thing as a calendar method of contraception. What does he represent? It is used when a woman does not want to have children yet (although not very reliable).
This method is considered one of the natural means by which pregnancy can be avoided. It was opened by two gynecologists - Japanese Ogino and Austrian Klaus.
How to determine which days you can not get pregnant using the calendar method of contraception?
It should be noted that its meaning is that fertilization occurs only for a few days from the moment of ovulation, thenis when the ovary leaves the egg. This period is considered the most favorable for pregnancy. The remaining days are conditionally called "sterile". Gynecologists say that not to conceive a baby is easy enough, you just need to refrain from sexual intercourse on “critical” days.
However, there are a number of ways to calculate which days you can not get pregnant. The first of them provides that it is five days before the onset of the menstrual cycle and five days after its completion. The essence of the second method is as follows: 14 days are taken into account before the date of the expected menstruation, eight days must be subtracted from this number and five days must be added to the end of the above physiological phenomenon - this entire period can be considered “dangerous”.
It must be emphasized that the risk of conceiving a child exists for a woman even during the “red” days. That is why in determining which days you cannot get pregnant, the calendar method of contraception cannot be considered one hundred percent effective.
Are there other ways to calculate sterile days? Yes, definitely.
A fairly common way to calculate which days you can’t get pregnant is the method of measuring basal body temperature. Again, it should be noted that its effectiveness is not always high. It is necessary to measure the temperature in the rectum daily using a mercury or electronic thermometer. Moreover, this procedure is done in the morning, immediately after waking up. All thermometer readings must be recorded. If the temperature in the rectum is less than thirty-seven degrees Celsius, then this indicates that the days have come when you cannot get pregnant. However, this cannot be considered an axiom, and, of course, there are exceptions to the rules.
In a huge number of situations before ovulation, the basal temperature is less than thirty-seven degrees Celsius. But it must be remembered that spermatozoa have a very high degree of survivability, which is why they can be active for several days. Therefore, it is far from certain that physical intimacy that happened between partners, in particular, five days before the onset of ovulation, cannot lead to conception.
Dangerous days, on which it is quite easy to get pregnant, can also be determined with the help of special tests. The above method is considered reliable, but quite expensive.
And, of course, be guided by your own feelings. During the period of ovulation, a woman feels pain in the lower abdomen, abundant vaginal discharge begins. These are clear signs that the risk of pregnancy during this period is maximum.
