Menstruation begins when you start ovulating. Ovulating is when an egg is released from the woman’s ovary and moves into the fallopian tube and onwards to the uterus where it can be fertilized by the male sperm. If the egg is not fertilized, blood and tissue from the lining of the uterus will be rejected as menstruation. It usually starts between 10 and 15 years of age. Depending on the woman, menstruation happens every 25 to 35 days. Some women experience pain, which happens because the uterus is contracting. This is completely normal.
