Birth control: A cycle every 21-35 days is considered normal. Lots of patients use various hormonal birth control methods for cycle control. Mirena (levonorgestrel) iud can even eliminate it in some. For those that prefer to avoid hormones Lysteda is a new drug that works well. If you are done having children consider an endometrial ablation.
