Normal vaginal bleeding is the periodic blood that flows as a discharge from the woman's uterus as a result of normal cyclic hormonal changes each month. Normal vaginal bleeding is also called menorrhea. The process by which menorrhea occurs is called menstruation.
Abnormal vaginal bleeding is a flow of blood from the vagina that occurs either at an unusual time during the month or in inappropriate amounts.
