Can I get pregnant if I have sex 8 days before my period?

Whether pregnancy is possible depends entirely on whether the sperm and egg can meet. Many people think that the period just after the menstrual period is an absolutely safe period because it has not yet ovulated, so it is not easy to get pregnant. This concept is incorrect. Because whether a woman's egg cells are perfect and the time of ovulation are related to the growth rate of the egg and the length of the menstrual cycle.

The normal physiological cycle of women is 21-35 days, the menstrual period is 2-8 days, and the ovulation period is 14 days before the next menstrual period. Assuming that your menstrual cycle is relatively short, about 21 days, and each menstrual period is relatively long, about 7-8 days, if you calculate according to the ovulation period 14 days before the next menstrual period, your ovulation period is exactly on the 7th day of the menstrual period, which is the time when the menstrual period is about to end. Having sex in this way is equivalent to having sex after ovulation, and the chance of pregnancy is very high.

Except for women with short menstrual cycles and long menstrual periods, ovulation time will be advanced, and whether pregnancy is possible is also related to the survival time of male sperm. It is generally believed that a man's sperm can survive in a woman's body for 3 days, and pregnancy is possible within 3 days of ovulation. However, scientific research has found that although sperm activity is relatively strong 3 days after intercourse and the chance of pregnancy is high, in fact, the survival time of sperm is not as short as 3 days. Some can reach 7 days or even longer. Thinking this way, even if we have sex a week before ovulation, we may still get pregnant.

If your menstrual cycle is 28 days (this is a relatively common menstrual cycle), and each time is 7 days, your ovulation period happens to be the 14th day of your menstrual cycle. If you have sex right after your period ends, that is, on the 8th day of your period, you can still get pregnant during ovulation, based on the one-week survival period of male sperm.

Therefore, the rhythm method of contraception is not safe and many people have suffered from it. There is no absolute dangerous period, only a relative dangerous period. Even if the menstrual period has just ended, it is still possible to get pregnant. Don't take chances and use good contraceptive methods.
