Hi, Novelon is a low dose combined oral contraceptive pill  .... To regulate your menstrual cycle, your doctor may recommend combination birth control pills — pills that contain both estrogen and progestin. These birth control pills decrease androgen production and give your body a break from the effects of continuous estrogen, lowering your risk of endometrial cancer and correcting abnormal bleeding. As an alternative to birth control pills, you might use a skin patch or vaginal ring that contains a combination of estrogen and progestin. During the time that you take this medication to relieve your symptoms, you won't be able to conceive.
