Before I started taking Yasmin I was the most level headed person you could ever meet. I never got irrational or cried for no reason. Now, since I've started taking it a few months ago, I feel anxious very often and cry A LOT. I don't like this new non-level-headed person I've become. Also, I am experiencing regular headaches. However, on a positive note: my boobs have gotten a little bit bigger, my skin is fine, and my periods have gotten MUCH lighter. Also, my libido is just as high as ever. So I'm not sure whether to stick with it or try an alternate method, maybe IUD. Thoughts?
