If you have intercourse too early, you don’t leave enough time for the body to recover, which will lead to the second wear and tear of the wound, resulting in the phenomenon of bleeding during intercourse. Secondly, infection of reproductive organs. Women in childbirth, the impact of the uterus, cervix and other reproductive organs are very large, usually need a long recovery period, and during the recovery period, it is also very easy to infect the wound, once the infection is easily triggered by inflammation of the reproductive organs, which will lead to bleeding caused by the stimulation of coitus.
