Menstruation does not go clean how to return a responsibility

A woman's menstrual cycle usually lasts three to five days, but the specific duration of menstruation varies from woman to woman due to the thickness of the endometrium, but generally does not exceed seven days. If the menstrual cycle is still wet after seven days, this situation is mostly caused by hormonal disorders or endometrial lesions, such as endometrial hyperplasia or endometrial cancer. At this time, the endometrium will show abnormal thickening and cannot fall off completely in a short time, so it will show vaginal bleeding and need timely treatment.
