Soaking through one or more sanitary pads within three hours
Need to use double sanitary protection to control menstrual flow
Need to wake up at night to change sanitary protection
Bleeding longer than a week
Passing blood clots larger than a quarter
This is a dangerous condition as it may lead to anemia, fatigue and shortness of breath. Mostly it is treated by medication or hormonal therapy.
