abnormal uterine bleeding
"I began taking this b/c 2 years ago because I was having a 10 day long period every other week. The pill worked perfect for regulating my hormones so that I would have a normal (4-5 day long) period once a month. I didn't have headaches, mood swings, weight gain, or any odd side effects. Only downside is my insurance began charging $50 a month for it so I had to stop using it and now have to switch. And now that I have stopped taking it my acne on my face, back, and chest has returned."
