Every woman has eggs in her uterus. When your hormones start to develop, once a month an egg goes down into the uterus and a blood lining starts developing. Your body is practicing having a baby in you. When your cycle is complete, the blood lining and egg flow out the vagina.

Girls have periods as a result of their reproductive system preparing for a potential pregnancy. Each month, the lining of the uterus thickens in anticipation of a fertilized egg. If pregnancy does not occur, this lining is shed through menstruation.
