I can identify with a lot of what people have posted here and glad I am not alone. I have been on and off NuvaRing for a few years now but this last time on it (about 8 months now) I have gained a significant amount of weight. I was a little bit heavy to begin with but I think the NuvaRing made it much worse and also harder to lose weight. I started working out in January as well as dieting and have been unable to lose even a pound. I finally went to the doctor and had some blood tests. My thyroid tests came back abnormal and when I saw an endocrinologist she attributed it to the birth control. I am also constantly tired. I have a white discharge all month long and barely get my period yet I feel like I have PMS all month long.
