polycystic ovary syndrome
"I've  gained  about 20 lbs in the past 3 months, a cup size & have tender breasts, but no other side effects. Was switched to this pill for my polycystic ovarian syndrome after using Lo Loestrin Fe for over year and had a lot of breakthrough bleeding. I used the Lo Loestrin in combination with Premarin until my doctor decided to switch me over."
