Is it not allowed to have sex during menstruation?

　　female Friends all know that the few days before menstruation and the few days after menstruation are the safe period for women. The so-called safe period means that sexual intercourse between couples during this period will not lead to unexpected pregnancy, including during menstruation. But it is better not to have sex during menstrual bleeding.

　　Not all women's menstrual cycles are the same length. Many people have a 28-day menstrual cycle, and some have a 22-day menstrual cycle. If your cycle is short, ovulation may occur a few days after your period ends. taking into account sperm The survival time in the fallopian tube can reach 3 days. In theory, it is possible for it to stay until the woman ovulates, allowing her to become pregnant in a short period of time in the late menstrual period.

　　some reasons healthy The problem causes women who still have continuous wetness in the late period of menstruation. Uterus The endometrium is already proliferating and ovulation is taking place, so protective measures must be taken during sexual intercourse at this time.

　　In a typical 28-day menstrual cycle, a mature egg is usually produced in the middle of the cycle, that is, on days 12-16. The ovaries excrete it into the abdominal cavity, where it is then sucked into the fallopian tubes, where it survives for about 24 hours. So only when sperm appears in the fallopian tube during this lucky period can pregnancy be possible. If the egg is not fertilized, the woman will have her period about 14 days after ovulation. During menstruation, another egg is developing in preparation for being released during the next cycle.

　　If estrogen is insufficient, ovulation bleeding may occur. Many women mistake it for menstruation, and it is entirely possible to get pregnant during sex.
