Ovcon and rocks

I'm on my second pack of Ovcon 35. I bled throughout the first pack pretty heavily (Dr. said normal) but no period during the green pills when expected. My breasts are so sore I can barely get my bra on without wincing in pain. They are also hard as rocks and a cup size bigger. I've gained 5 lbs even though my eating habits are the same. My Dr. put me on these to shrink an ovarian cyst but I'm not sure the side effects are worth it....am going to ask to be switched to lower estrogen pill.
