Bleeding the day after intercourse may be due to the occurrence of early menstruation caused by intercourse. If intercourse occurs before the upcoming menstruation, the process of intercourse may accelerate the shedding of the endometrium and cause early menstruation. In this case, women need to observe their menstruation and if it is not too different from the usual menstruation, no special treatment is needed. If there are no problems with the two tests, no special treatment is needed. If there are positive test results, colposcopy should be referred. Bleeding after intercourse can also be caused by cervical polyps, which need to be removed and sent for pathological examination after surgery.
