N92.1: Excessive and frequent menstruation with irregular cycle

Your menstrual bleeding has changed. You bleed too much.

The uterus consists mainly of a layer of muscle and a lining of mucous membrane (mucosal lining). The mucosal lining receives a good supply of blood and steadily increases in size. Unless an egg is fertilized, a large part of the mucosal lining is shed and replaced. The menstrual bleeding starts when the mucosal lining is shed. The uterus is connected to the vagina. During your menstrual bleeding the mucosal lining is discharged through the vagina to the outside of the body along with some blood.

Your periods are infrequent. Your menstrual bleeding has changed. Your periods are more frequent, heavier or longer than usual. You may also experience additional bleeding between your actual periods.
