I have been on Yasmin for three years. I was put on it after I had an out of control year long period after being given a medication during knee surgery. Since being on Yasmin I have had several UTI infections including one that led to Clostridium Difficile and hospitalization after being on so many anti-biotics. I have had severe weight gain despite all imaginable efforts to lose it and I am always tired. I had no idea other people had the same side effects as me until I started to research other birth control pills to switch to.
