What counts as a 'normal' cycle?

A menstrual cycle is counted from the first day of one period to the first day of the next. For teens, anywhere from 21 to 45 days is considered typical — and it's common for that number to bounce around while your body finds its rhythm.

Why your first year or two might be unpredictable

Right after your first period, your hormones are still settling into a pattern. Skipped months, unusually short or long gaps, and changes in flow are all common during this adjustment period — it doesn't necessarily mean anything is wrong.
