What is Polymenorrhea?


Updated June 10, 2014

Definition: Polymenorrhea is a type of abnormal uterine bleeding. Polymenorrhea occurs when the menstrual cycle is less than 21 days long. It is sometimes difficult to distinguish polymenorrhea from metrohhagia; however, bleeding that occurs at regular intervals less than 21 days apart is usually polymenorrhea. Normal menstrual cycles are from 21 to 35 days long. Day 1 of the menstrual cycle occurs the first day you experience any amount of bleeding.
