My doctor switched me to Yasmin one month ago because I had ceased to get periods on Levlan. Levlan worked great for me for two years; I had no side effects. However, just one week into Yasmin I noticed striking changes. My sex drive tanked.. I now find it incredibly difficult to orgasm. I also started getting bad headaches and I've never had trouble with headaches in the past. I have to urinate ridiculously frequently. I am stopping Yasmin today after only one month. It's a miserable pill. I am angry that my doctor didn't warn me about this drug! I hope that things go back to normal for me quickly. I would recommend women avoid Yasmin.
