Yasmin and boob job

I've been on Yasmin for about 5 or 6 months..The first couple of months were fine, I still had energy, a little added size to the breasts, cleared my acne completely. Now people are asking my if I got a boob job, they're freaking huge! Or if I'm pregnant because it looks like I gained about 20 pounds and I feel awful about myself. I'm an avid gym goer and I can't drag myself to gym if my life depended on it, or the fact that I have a layer of fat all over my body that developed after starting the pill. I read another comment about little red bumps someone was having problems with..me too, some of them are itchy, and my acne is slowly coming back. I'm stopping the Yasmin as soon as I get home from vacation next week, hopefully I won't have any of the side effects I've read about after people have come off the pill.
