A word for heavy menstrual period?

Answer 1

The medical term to mean a heavy period is Menorragia.

Menorragia is when the menstrual flow is over 80ml, although this is still fairly light compared to many people's menstrual flow. If you're leaking through ultra tampons or maxi pads within an hour then talk to your doctor to check everything is okay and get Tranexamic Acid to reduce flow, also consider a menstrual cup which hols more flow and can even lighten your flow too.
