If there is vaginal bleeding after intercourse, then we should first rule out whether it is before or after menstruation, because at this time there may be some blood in the uterine cavity that is not clean, and after intercourse there may be a little blood in the vagina, which can be ignored first. The second situation is to rule out cervical lesions, one is cervicitis, if cervicitis is present after intercourse, vaginal bleeding may occur. The second is cervical polyp, which is soft and may cause vaginal bleeding after intercourse. If you have vaginal bleeding after frequent intercourse, it is best to go to the hospital for a checkup to rule out cervical cancer or cervical precancerous lesions and to do cervical cancer screening.
