"i have been on nuvaring for 6 years now. i got on it when i was 18 and now i am 24. no major side effects- i think my small weight gain was due to college more than nuvaring. the only problems i have had were when i forgot to put the new ring in after 7 days. the first time i did this i was 3 days overdue on putting it in. i consulted my doctor&#039;s nurse and she said it would be okay to leave it out that month and restart as normal the next month. i was fine until i put it back in the next month. i got migraines and extreme nausea. it was terrible.
