Bleeding two days after menstruation is considered to be caused by the cervical opening not being completely closed, which is also known as the phenomenon of menstruation returning. If the amount of bleeding exceeds the normal amount of menstruation, you need to take oral medication to stop bleeding, if it is only a small amount of bleeding, spot bleeding will usually be cleaned up in about three days. During this period, you should pay attention to the cleanliness of the vulva, wash the vulva every day, prohibit sexual intercourse or go to the hospital for a repeat ultrasound to see if there are polyps in the uterine cavity and other phenomena caused by bleeding. If there are polyps, you need to do hysteroscopy to take out the polyps, and use anti-inflammatory drugs to stop bleeding. At present, we should do gynecological examination and ultrasound examination first, and then use medication to stop bleeding.
