how long will your period last during a heavy flow
What Is Menorrhagia? Menorrhagia is the medical term doctors use to describe heavy menstrual bleeding or periods that last an unusually long time. It's normal to lose about 2 to 3 tablespoons of blood during your period. And the average woman's period lasts 4 to 7 days. But losing twice as much blood as normal or having a period that lasts longer than 7 days may be a sign of menorrhagia.
