Can getting too much exercise delay a girl's first period?

ANSWER

Pushing your body too hard physically also can make your first period come late. This can happen with ballet dancers, runners, or other athletes. Intense workouts burn lots of calories and can leave very little body fat. Mix that with competitive pressure, and they can postpone your period until you’re well into high school.
