Yaz and migrane

I'm 2 rows into my 2nd pack of Yaz. It's my first birth control and was told by my doctor to give it a try a couple months and let my body try to adjust. Toward the end of the first month I got very moody, much unlike myself, annoyed with small things, and really upset my boyfriend and snapped at him unjustly. Off the pill, I had max 3 day periods, my first one on Yaz started the morning after my last pink pill of the month and lasted 7 days steady. My mood was the worst toward the end of that, and I was crying over things I normally wouldn't tear up about. Now, 2 weeks into the 2nd month, I'm cramping up already & have a noticeable lack of libido. I am thinking about switching, but feel like 3 months would be appropriate to try to adjust. Nice to know I'm not the only one with these symptoms. It's also nice to know it could be much worse, for example, I've never had a migraine, and haven't noticed any additional headaches since I started. Just hoping I adjust soon, because I'd hate to change and go through another readjusting phase.
