"no problems - at first had great sex drive, 4 day periods, no cramps, light. no headaches or mood changes like with other birth control pills. the pills are not expensive. did have a lot of yeast infections every month on the time of my period. stopped taking it because my sugar got high and blood pressure was high. if you are a diabetic or have high blood pressure you have to be monitored by your doctor. this pill was not for me but every body is different.
