It is best not to have intercourse when your period is almost over. The menstrual bleeding is not yet complete, there is still a small amount of bleeding at this time, and the environment inside the vagina is not suitable for sex, which itself may have an impact on your health. If you have sex at this time, it is likely to stimulate further increase in bleeding, or the bleeding will not end, thus directly affecting the menstruation. The process of sex also increases the chance of infection, because the immunity is low during the process of vaginal bleeding, which may cause inflammation, so sex at this time has a very obvious impact on health.
