Irregular cycles are a hallmark of perimenopause. Bleeding patterns can also change. At various stages, women may experience prolonged menstrual bleeding for longer than nine days, a particularly heavy menstrual flow for three or more days, or shorter and lighter periods.
Mid-cycle staining is also more common in perimenopause, and many women start to experience brown discharge several days before menstruation actually begins. Some women will spot for multiple days between periods as well.
Irregular bleeding and staining are natural at this stage of life, as hormone levels change, and there is often no medical need for treatment. However, a woman may experience difficulty, even if just in the context of niddah observance. In this case, she may wish to consult her healthcare provider about possibilities for alleviating these symptoms. The most effective treatments offered by conventional medicine are generally hormonal replacement therapy or hormonal contraception.
Increased bleeding (greater-than-usual frequency, length, or volume for over three months) should be evaluated by a healthcare provider, to check for underlying conditions that can or should be treated. For example, women in perimenopause are more likely to develop fibroids, polyps, or other uterine growths that can lead to irregular or heavy bleeding. Treatment for these types of growths may include surgical removal, along with hormonal management of the bleeding.
