Since I started taking Ovcon 35 I cramp and I had breakthru bleeding/period that lasted 2.5 weeks. I went to the OBGYN and he said remain on it one more mth...and the biggest downfall is the weight gain. I am miserable with the weight gain and I am seriously dieting and nothing seems to shed the weight off since I started taking this pill. Therefore, I plan to stop although I do not want to get pregnant right now if and when that happened it would be ok considering I am happily married and do not have any children yet. I just want to plan that and I want to be able to fit in my clothes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I am sick of dieting and due to a BC PILL I am fat! I can't take Othro Tri Cyclen which I did for 7 yrs due to break thru bleeding. I wish things were simple but I guess they are just not once you hit your 30's!
