I was on Yasmin for over 4 years with no problems. It actually helped me lose weight, lessen my HEAVY flow and decrease my cramps. I originally started it for the fact that my periods usually lasted over a week. I loved this pill. At my last exam, my gyno prescribed Yaz. I didn't notice much of a difference, though I still loved Yasmin and my doc gave me the option of going back at any time. After reading this forum, I notice that maybe my headaches that I never get I had a lot of after starting. This side effect did not last long, maybe two months. I had a positive experience. Everyone's body reacts differently, so i'd say give it thre months and see how you do.
