It's not always a good idea to ask questions regarding birth control pills - there never seems to be one pill that works the same for everyone woman. I didn't like Yasmin. It didn't clear up my skin and didn't help me lose weight. I in fact found it very difficult to lose while on the pill. I read many accounts from women saying it helped them lose, some saying they gained, etc. If you want to try it you should. I am on glucophage now and that has made my periods back to normal.
