Why does pregnancy occur during the safe period?

For newlyweds, sex life is a very important part of the relationship. If there are problems in the sex life, it will lead to big problems between the couple. We often hear about divorce or infidelity because of such problems. But this also brings a problem, which is pregnancy. Many times, newlyweds will suffer from unexpected pregnancy due to this problem, even during the safe period. Today I will introduce to you the problem of unexpected pregnancy during the safe period.

There are many examples of accidents during safe period contraception. They are not due to irregular menstruation, but are more complicated and difficult to master. During the safe period, you can avoid getting pregnant without taking any contraceptive measures. The female cycle is from the first day of the last menstrual period to the day before the next menstrual period. The cycle ranges from 23-35 days. Although ovulation only occurs in one day, the truly safe period is only a few days. The reason is that there are too many uncertainties. Sperm and egg have a lifespan. Don't believe what netizens say, that sperm lives for 4 days and egg lives for 3 days. There is no problem with the egg after 3 days, but there is a problem with the sperm after 4 days. There are huge individual differences. That is just the average level. Medically, there are examples of sperm surviving for 8 days. The 14th day before the next menstrual period is the ovulation day. The statement that it is dangerous 5 days before ovulation and 4 days after ovulation is also a general statement. The problem is that no one knows exactly when you ovulate unless you go to the hospital to measure your ovulation, measure your basal body temperature, or use ovulation test strips every cycle. Ovulation test strips are not reliable either. Contraception is unrealistic. The best option is 7 days before and 7 days after ovulation. If you mark each menstrual period on a calendar and calculate the cycle of the previous month, after a few months, you will find that the number of days between periods is not always the same. It is rare for it to be 28 days every time. The most likely scenario is that this time it is 27 days, the next time it is 30 days, and the next time it is 29 days. There is a longest cycle and a shortest cycle.

I wonder if you have remembered the introduction above. Although sexual life is important for newlyweds, it should be moderate and necessary contraceptive measures should be taken to avoid accidental pregnancy.
