Understanding Periods
Having a period is a normal, healthy part of becoming and being a woman. A period is the result of a cycle that takes place inside a girl’s body. This menstrual cycle makes it possible for women to have babies. The cycle begins with ovulation, when an egg is released and begins its journey.
An Egg Is Released
-
During each cycle, one egg grows and is released from an ovary. It finds its way to the fallopian tube.
The Egg Travels Through a Tube
-
The egg moves through the fallopian tube toward the uterus. (If the egg and a man’s sperm meet here, a woman becomes pregnant.)
The Lining Thickens
-
The lining of the uterus grows thicker. This lining is made up of blood, tissue, and fluid. (The lining will nourish a growing baby during pregnancy.)
The Egg and Lining Are Shed
-
About once a month, the egg and the lining of the uterus are shed through the vagina. This is called a period. (A period does not happen during pregnancy.)
