N92: Excessive, frequent and irregular menstruation

N92.4: Excessive bleeding in the premenopausal period

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.

You have stopped having regular periods. You are at the transition to the point where your periods will stop entirely. Periods stop when you reach the menopausal transition. Most women stop having regular periods at this point. After a while they stop completely. Your periods are too heavy, too long or too frequent. Or you have additional bleeding.
