Why do girls have periods
Girls have periods so they can reproduce. A period is when a woman's eggs drop from her ovaries and into her womb. The womb then lines itself with a cushioning for the baby that could come from the egg, but since most of the time you are not having a baby, the lining sheds away in the form of blood and the egg comes out with it.
The average age for a girl to get the period is 12 years old. This can vary for different girls, as everyone grows up at their own pace.
