Most girls get their first period between the ages of 10-16, but there is no 'right' time. Your period will start when your body is ready. If you haven't started by 16, you may want to talk to your doctor. As a rough guide, your period will probably start:about 2 years after your breasts begin to develop; within a year or so after you've developed pubic and underarm hair; after you start to notice some vaginal discharge in your pants. The information being provided does not substitute for medical advice from your doctor or care giver.
