Once the certain age is reached, the female's body is matured enough to have her eggs fertilized. Each month, her body thinks that she is going to get pregnant. Once the egg(s) that has been distributed has not been fertilized around 25-28 days, her body flushes out all the blood and cushioning her body was preparing for the baby. This is the discharge females have called periods.
