"i have been on the nuvaring for one week. i came off of tri sprintec. i was so hormonally messed up from going to a combination pill to an estrogen only back to a combination. i bloated out and looked like 6 months pregnant. so i got off all birth control for one month and inserted the nuvaring when my period started. i have been constantly nauseous with no appetite at all. i also have severe diarrhea. i&#039;m still going to give it a try for another month to see if those side effects wear off. every time i start a new birth control pill i get sick to the stomach. so this must be the case. i love it&#039;s convenience. i have no other side effects."
