Heavy menstrual periods (menorrhagia) are periods in which bleeding is heavier or lasts longer than normal. You may pass large blood clots and have to change pads or tampons often. Or your periods may last longer than 7 days.

With heavy menstrual periods (also called menorrhagia), you may:

  • Pass large blood clots and soak through your pads or tampons often.
  • Bleed for more than 7 days. (A normal period usually lasts 4 to 6 days.)
  • Have menstrual cramps.
  • Heavy periods may disrupt your life. But in most cases, they aren't a sign of a serious problem.

Still, it's a good idea to see your doctor. A doctor can suggest treatments to ease your symptoms and make sure that you don't have a serious condition.
