menstrual cycle is the series of changes a woman's body goes through to prepare
for a pregnancy. About once a month, the uterus grows a new lining
(endometrium) to get ready for a fertilized egg. When there is no fertilized
egg to start a pregnancy, the uterus sheds its lining. This is the monthly
menstrual bleeding (also called menstrual period) that women have from their
early teen years until menopause, around age 50.
