I just started using Yasmin 15 days ago and in the second week of...

the leg cramps may be caused by the potassium absorption by Yazmin. I had the same thing happen, started taking potass and it went away. I have not had any other side effects.

I had this same symptom. The leg cramps would keep me up at night. I got extremely lucky to have a campus clinic with no wait, I went because I was having trouble breathing but my leg was killing me. The nurse was really helpful and when she looked at my leg sent me directly to the hospital. I had developed blood clots in my leg and had been passing them into my lungs (hence the trouble breathing). Be very careful....it is sort of easy to tell if blood clots are the issue, your leg will be hot! especially around the site, you may also notice red streaks on your leg and there will be swelling. If you are still having issues...DO NOT MASSAGE OR TRY TO "LOOSEN" go to the hospital...these are extremely dangerous and can kill you. Thanks to the lovely side effects of Yasmin I will be on blood thinners forever, I will forever have my PT/INR (clotting scale) tested.
