Bleeding a few days after intercourse does not mean that there is some relationship with intercourse. Generally, bleeding during intercourse is a small amount of bleeding during intercourse, or a small amount of bleeding the day after intercourse, which may be related to intercourse. However, a small amount of bleeding after intercourse may not necessarily be caused by intercourse, but may be caused by inflammation of the cervix, inflammation of the vagina, cervical canal hyperplasia, endometrial polyps, fibroids, inflammation of the endometrium, as well as oral medication and endocrine hormone imbalance, all of which may have a small amount of bleeding. Such bleeding is recommended to be observed for about three days, and if it ends in about three days, there is no big problem. However, if such bleeding is still present for more than three days, or even seven days, go to the hospital and register with the gynecologist, have an ultrasound done to determine if there are any abnormalities in the uterus, both adnexa and vagina, and take certain oral anti-inflammatory and hemostatic drugs according to the situation to help the disease get better quickly.
