Menstruation (menstrual cycle) is also referred to as a "period." When a woman menstruates, the lining of the uterus is shed. This shedding of the uterine linking is the menstrual blood flow. The average menstrual cycle is 28 days. There can be problems with a woman's period, including heavy bleeding, pain, or skipped periods. Causes of these problems may be amenorrhea (lack of a period), menstrual cramps (dysmenorrhea), or abnormal vaginal or uterine bleeding. There are a variety of situations in which a girl or woman should see a doctor about her menstrual cycle.Read more: Menstruation (Menstrual Cycle) Article
