In brief: Depends

Usually girls start having their period when they are 11 or 12 years old.
Their systems are immature so maybe until 18 they will have irregular cycles.

In brief: It varies

There are a lot of factors that can impact a woman's cycle.
A normal, mature hormonal system would have a period every month on average (21-42 days).
