I have been taking Yasmin for a little over a year now. I had really bad mood swings and was extremely emotional during the first month, but ever since then I have had no problems. My period is a lot shorter and lighter, I have no cramps, and my skin has almost completely cleared (and it was really bad before). However, my breast size did not increase whatsoever, and seeing that I am A cup, I would have loved that. Reading all these comments makes me wonder why I did not have that side effect! Besides that, I didn't have any weight gain or notice any other problems! Hope this helps!
