When should I see a doctor about my period?

You should see your doctor if:

  • you have not started menstruating by the age of 15, or by three years after breast growth began, or if breasts haven't started to grow by age 13
  • your period suddenly stops for more than 90 days
  • your periods become very irregular after having had regular, monthly cycles
  • your period occurs more often than every 21 days or less often than every 45 days
  • you are bleeding for more than seven days
  • you are bleeding more heavily than usual or using more than one pad or tampon every one to two hours
  • you bleed between periods
  • you have severe pain during your period
  • you suddenly get a fever and feel sick after using tampons
