A girl will get her period from ages 9-18. Your period should come once a month for about 5-8 days. If you miss your period it means you might be pregnant night not. the reason a girl gets her period is when you have a baby in your womb the baby gets a certain amount of blood a month (different for everyone). but the baby is not there so the blood comes out. some people feel tingling. Sometimes a lot of blood comes out. It will happen about every 1-3 hours for 5-8 days as mentioned before to stop the blood you either use tampons or pads,
