Did anyone else have issues (especially weight gain) when they stopped taking the pill?

I am 27, and I stopped taking the pill last fall after 10 years of taking it. I was on several different brands throughout the years, and I finally stopped so that we could try for a baby. I noticed a lot of changes very shortly after taking the pill- some I had anticipated, and some I had not. I have had several breakouts, which I had been warned about, and severe pms, also expected. What I did not expect was the weight gain. I gained 20lbs within 2 months of stopping the pill, and it has not gone away. I exercise and eat healthier than I ever have, and the scale doesn't budge. I'm fighting to even maintain my current weight. I read online that after stopping the pill a third of women lose weight, a third do not notice a weight change, and a third gain weight. Has anyone else had this experience? What can be done to help? If I just have to wait it out, how long did it take others with this issue?
