"i have been on nuvaring for a year now and it is the most effective and worry free method of bc i have ever used. i did gain some weight on it but i&#039;m a stressed out college student. while i think the ring is great has had some adverse side effects for me personally. i have terrible back pain with my periods even thought they are short lasting 3-4 days. i have such a decreased sex drive and it is so affected and sometimes puts a strain on my relationship, (i have been with him for 3 years so he&#039;s been thru the bc changes and has noticed himself)..and the ring has probably made my aniexty worse, i did not have anxiety problems until using the ring, they are mild episodes but still annoying to have. havent gotten pregnant so it&#039;s good for that"
