Complications – Menorrhagia
Heavy vaginal bleeding, known as menorrhagia, may be either prolonged menstrual flow (greater than 9 days) or excessive flow which may occur at the time of menstruation or in between periods. Most women during a normal menstrual cycle can go several hours without changing their pads. If your pad is saturated and needs to be changed every one to two hours, or you need to get up at night to change pads, you should consider this abnormal and have this evaluated by a physician.
Bleeding that occurs in between periods may also be due to abnormal conditions, although some women normally have a day or two of spotting midcycle during their time of ovulation. This may also be normally seen when starting birth control pills or changing to a different pill. You may also experience a change in bleeding patterns during times of increased stress. Under these benign circumstances, bleeding in between periods should not be persistent. If it occurs consistently, see your physician.
Any vaginal bleeding that occurs after menopause should be considered abnormal and needs to be investigated immediately.
