Your first menstrual period is called menarche. It usually happens around age 12. But it may start earlier or later. Your period is a part of your menstrual cycle. This cycle is a series of changes your body goes through to prepare for a possible pregnancy. Having a period means you can get pregnant if sperm fertilizes an egg through sex.
At first, your period may not come every month in a regular pattern. It could be as long as 2 years before yours has a regular pattern. Periods usually occur about every 4 weeks.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if you have any problems.
