"i was off birth control for a while considering getting pregnant. i had used other types of birth control before, the pill, the patch, etc. i decided to get back on birth control but didn&#039;t want to worry about taking a daily pill so i requested the nuvaring. when i started the nuvaring i felt it inside my body and had a lot of cramps. a few days later i started experiencing more cramps and very strong upper stomach pain. they were so bad i missed work for a week. finally i ended up going to the er and they couldn&#039;t figure out what was wrong. i finally asked the doctor and it was the nuvaring side effects."
