Pregnancy is without a doubt the most wonderful time in the life of any woman. After many years, mothers with warmth and trembling recall their growing tummy with yeast and the first movements of the long-awaited child. But due to some circumstances, pregnancy in a woman’s life can be not so much unwanted as unplanned. In order to prevent such a pregnancy, women use various methods of protection. One of them is calendar.
The essence of the calendar method is to calculate the most probable period for pregnancy in order to limit sexual contact with a partner at this time. Since the method is based on natural phenomena, it is also called physiological. It is believed that getting pregnant these days is almost impossible due to the fact that the body is not yet ready for pregnancy. Is it so? Let's try to figure it out.
The female genital area develops cyclically. Almost every month, an egg matures in a woman’s body . During ovulation, the follicle bursts, and the egg enters the abdominal cavity, where it is picked up by the fibers of the fallopian tubes and drawn into them. The egg life is quite short - up to about two days. If a sperm is found on the way of the egg, then fertilization occurs and the unborn baby descends into the uterus and attaches to its wall, enveloping the villi of the endometrium amiably. As we can see, in the body of a healthy woman, the whole process from beginning to end is designed to reproduce its own kind, so the likelihood of pregnancy during ovulation is very high. If fertilization has not occurred, then the egg is removed from the uterus during menstruation - the body carries out cleansing, preparing for the next cycle. These are the safest days for pregnancy.
It is logical that for protection you need to know the time of ovulation - safe days for pregnancy. Some women, however, their percentage is very small, they feel the follicle rupture - this happens approximately in the middle of the cycle. Other women just have to count the middle of the cycle and at this time limit sexual contact. But how to count ovulation days if the cycle is inconsistent? After all, the female genital area is very sensitive and susceptible to external influences. Stress, relocation, past illnesses - all these factors can cause a shortening or lengthening of the cycle. Already with this unfavorable factor, it is worth doubting whether there are safe days for pregnancy in general? Another danger of becoming pregnant is that when calculating the safe period, you need to take into account the life expectancy of sperm cells, which many forget. In some cases, sperm do not lose their ability to fertilize, even eight days after getting into the uterus. That is, even with relative calm, there are still dangerous days for pregnancy - a weekly period of sperm viability.
Typically, women for a greater confirmation of ovulation keep a graph of basal temperature, which must be measured every morning at the same time, getting out of bed. When she makes a sharp jump - in ovulation decreases and immediately rises. But here there are difficulties, since an increase in temperature in the rectum can be caused not only by ovulation, but also by some diseases.
In fact, there are safe days for pregnancy, but calculating them is quite difficult. To do this, you need to monitor the duration of the cycle for a year, and even then those women in whom it is stable. In addition, it is advisable to measure basal temperature and always remember that this method of pregnancy protection is the most difficult in its application.
