How many days it takes for a woman’s menstrual bleeding to end varies from person to person. For example, if a woman is bleeding during intercourse on the last day of her period, but the intercourse does not cause symptoms of pelvic infection, the bleeding may last for about 2 days and then end completely. However, if a woman is having intercourse, resulting in endometrial inflammation will cause prolonged menstrual periods and lead to symptoms of pain in the lower abdomen, so the bleeding at this time may not be able to naturally clean up in 7 days, or even 10 days, and antibiotics need to be used for anti-inflammatory treatment, and after the inflammation is basically under control, the menstrual blood will be cleaned up naturally. Bleeding caused by infection will have a distinct odor, and there will also be an increase in the amount of blood.
