I have been on Yasmin for about 3-4 years. First couple of years was great and it worked for me to have a period. Over the last few years I have had weird issues. Light bleeding for eight weeks, pain on the right side. Had an endometrial biopsy that came back fine. Was put on Yasmin and Provera together. Have been having anxiety issues which was caused by Provera when I was on it a few years ago. Went back for for major pain on right side, had a CT Scan, doctor said it showed some white spots on the ovary that typically mean benign or it could be a dermoid cyst and it was nothing to worry about. Over the last few months have had major back and hip pain that is bad while on the Yasmin and Provera and goes away when off for the week. Have seen a new doctor, am scheduled for a MRI tomorrow and tested for PCOS and will have the results next Tuesday. I do not know if my symptoms are from the Yasmin or not, but I am about to take my self off of it to see if things improve. Also have had the tingling arms and legs and hair loss over the last few months. I can not clearly confirm the symptoms are caused by birth control as I have looked all over the internet and found very little. I have found one article that said arm and leg tingling while on birth control is a symptom b/c of the reducing of B-12 while on birth control and one article that stated that a study overseas showed that women on birth control experience back pain more then women not on.
