Even if your period is about to clear, you should not have intercourse as long as it is not yet clear and there is still a small amount of vaginal bleeding. The reason why there is still a small amount of bleeding is because the endometrium has not been completely repaired, if intercourse is likely to lead to reproductive tract infection, which may cause repeated lower abdominal pain or increased vaginal discharge, and may even lead to infertility, so you should not have intercourse before your period is completely clean, and it is best to have intercourse 3 days after your period is completely clean, which will not cause corresponding effects on your body. Although menstruation is a normal physiological period for women, if you do not pay attention to your life and medication during menstruation, it may affect your menstruation and cause disruptions or changes in the amount of menstruation, so you should pay proper attention during menstruation.
