Menorrhagia is a medical term for abnormally heavy or long-lasting periods. If you bring this up with your pediatrician, doctor, or gynecologist, they may need to do some blood tests to look at your thyroid function or iron count. The purpose of the blood tests is to rule out anemia, which makes you feel tired and weak.

Symptoms of Menorrhagia (excessive, heavy bleeding) are:
  • Soaking through one or more pads or tampons every hour for several hours in a row
  • Needing to use 2 period products at once to control your menstrual flow
  • Needing to wake up to change period products during the night
  • Bleeding for longer than a week
  • Passing blood clots larger than a quarter
  • Needing to restrict your daily activities due to heavy menstrual flow
  • Symptoms of anemia, such as tiredness, fatigue, or shortness of breath
