Irregular Periods at 13: Causes, Concerns & When to See a Doctor

It is normal for periods to be irregular for the first few years after they first start. This is because the hormones that control the menstrual cycle are still developing and finding their balance. As you get older, your periods should become more regular.

However, if you are concerned about the irregularity of your periods, you should talk to your doctor. They can assess your situation and determine if there is anything wrong.
