NuvaRing

Has anyone tried or is on NuvaRing? I just went on the pill back in June and started having stomach problems about a month later. After tons of testing for gastrointestinal problems, they think the issue may be my birth control pill. I had an appointment with my gynecologist yesterday afternoon and she said my best option is to try the NuvaRing. Can anyone give me a little insight as to their experiences with NuvaRing? Pros/Cons? Thanks!🙂
