abnormal uterine bleeding
"I have been on Seasonale for over a year now, and it is the only birth control that has actually worked for me, after going through 6 other brands. I went from having very heavy periods and cramping for 7 days, to having a very light (hardly there) period every 3 months. It also managed to clear up the cystic acne that came along with it. My only issue with it was that for the first month or two on the pill, I did have some spotting and bleeding, but it quickly went away, and haven't had any bleeding since then. Other than that I haven't experienced any other symptoms, and I highly recommend Seasonale!"
