Normally, a woman’s menstrual period clears within 2-8 days, so a brown discharge on the 7th day of menstruation that clears completely by the 8th day is within the normal range. If a woman’s menstrual period does not clear within 8 days, it is an abnormal condition and requires clinical examination to determine the cause and treatment. An internal gynecological examination should be done to see if the bleeding is coming from the cervix or the uterine cavity, and to see if there are any organic lesions such as polyps or tumors in the vagina and cervix. If the bleeding comes from the cervix and there are organic lesions, surgical excision and pathological examination are required. If there are no organic lesions, cervical TCT and HPV examination are required to determine if the bleeding is caused by intraepithelial neoplasia of the cervix or cervical cancer. If the bleeding comes from the uterine cavity, ultrasound should be done to observe the thickness of the endometrium. If the thickness of the endometrium is normal, caffeic acid or Yunnan Baiyao can be used to stop the bleeding.
