I knew there was something wrong with me, but I wasn't sure what it was! I am so glad I decided to research YASMIN. Since I have been on it, I have gained 15 lbs, I have horrible headaches, I am always in crazy mood swings. I never had these troubles before and never gained weight like this. I didn't change my eating regimen so I knew it was something else. I even train 3 times a week with a trainer and the weight is sticking. I will be finding another birth control method!!!
