abnormal uterine bleeding
"I was prescribed this because of heavy bleeding with my period because of a fibroid. At first I was amazed because as soon as my period started I took them and it stopped within a few hours or a day. Then I started bleeding again after two weeks. I took it again. Two weeks later, spotting again. Now my period was heavy, but it was predictable before megace. The only time I was ever late was when I was pregnant. But now, its all over the place, when I don't take the megace at  the start of bleeding, it will be nonstop. I've had  a light period for the past two weeks! Doesn't work anymore and causes weight gain. I hate it."
