Within about 8 days of starting Yaz, I developed muscle pain all over my body, but especially in my legs and shoulders. Sometimes it felt like muscle cramps, sometimes like a crawling feeling, sometimes like a pinching, sometimes like a knot. Blood tests and a Doppler test showed no blood clots, but I went off the pill anyway. The symptoms started improving after a few days, and mostly went away within a few weeks. But then I came down with extreme itching and discharge, and trips to four different doctors revealed no infection. That finally cleared up after about two months. Now I'm on a different pill, and unfortunately the muscle pain is coming back. So I guess hormonal birth control might not be for me, but like someone said, this is not easy to deal with in a committed monogamous relationship. I'm going to take a break from all hormonal birth control and hope that the return of the muscle pain was just because my body isn't ready yet after the Yaz.
