Starting your periods

Periods
Your periods start anywhere between the ages of 9 and 16. When this happens, it shows you’re in the final stages of puberty – becoming physically and sexually mature.

At first, your periods may be irregular.  They may not come every month (roughly 28 days), but more often (every 3 weeks) or less often (every 6 weeks). Don’t worry, this is normal. It can take up to three years for a woman's period to become regular.

Remember every woman's menstrual cycle is different. A way to figure out what is a regular menstrual cycle for you, is to jot down the first day and last day of your period on a calendar for a few months.
