"hi there i decided to come on a write a review for this product because i see a lot of negative reviews. nobody really takes the time to come on and review something when they really love it. i have been on the nuva ring for about 6 months now and i love it. i&#039;m anemic and have endometriosis, so my periods are extremely painful. and the nuva ring takes care of all of that. it&#039;s very effective in preventing pregnancy. i see some people talk about blood clots. it&#039;s a risk in any birth control. you must maintain good general health with any hormonal substance. i also saw people complaining they could feel it or it was coming out. to be honest you can&#039;t just put it in like a tampon, you have to completely lay on a bed and relax yourself."
