abnormal uterine bleeding
"My doctor prescribed Avaine to me after I was suffering from very severe anemia caused by my ridiculously heavy and painful period. I used to bleed heavily for 10-12 days, meaning I would have to change my pad every 30 minutes or less. This is the first and only birth control pill that I have taken and I am only taking it for anemia (but consider using it for it's original purpose) and it has been a God send. My periods are significantly less painful, lighter, and the side effects are not nearly as awful. I have been taking the pill for about 3 1/2 years now and other than some nausea, spotting, and discomfort for the first couple of months, it's been great. Mood swings occur, but so has breast enlargement. Fair trade in my book."
