Are Irregular Periods Common in Teens?

Your child getting her period is a milestone moment marking adolescent development. Dr. Sarah Garwood, Adolescent Medicine Specialist at St. Louis Children’s Hospital, describes what to expect next and explains that irregular periods are common up to the first two years. While irregular periods are common, there are other signs of menstrual cycle irregularity that can cause them to miss regular activities and may require a visit to a doctor. To prepare them for this phase in their life, it is important to start the discussion with your child.
