Is it normal for a girl to have her period?

Yes, it is perfectly normal hun. A woman's period (menstruation) is normal vaginal bleeding that is a natural part of a healthy woman's monthly cycle. Every month, in the years between puberty (typically age 11 to 14) and menopause (typically about age 51), your body readies itself for pregnancy. A period is when a woman's body releases tissue it no longer needs. This tissue comes from the uterus, which is where a baby (fetus) can develop in the female body. Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant.
