Is it normal to have your period the first time, and then not again for many months?
It's common to skip periods or to have irregular periods, especially in the first 2 years after your first period.
Irregular periods are not unusual, especially in the first 2 years after menarche (the first menstrual cycle). Serious illness, rapid weight change, excessive exercise, or significant stress can also make your period more unpredictable. That's because the part of the brain that regulates periods is influenced by bodily changes like these. If you ever have any concerns, we recommend that you speak with your doctor.
