Is it allright during menopause to have a extremely heavy period after a large gap in menstrual cycle? The period is terribly heavy.

It depends. If u have been a year or more since your last period, any bleeding is abnormal. If it is less than a year it may be normal but not good.The uterine lining is still seeing estrogen and growing and can become so thick it starts breaking off without the maturation that progesterone causes.This leads to heavy and prolonged bleeding.U need to see ur PCP or GYN for evaluation and treatment before anemia.
