My daughter uses the Nuvaring also -- we felt it was better because she didn't have to remember to take the pill and she wasn't drugging the whole body (we already knew she didn't tolerate high doses) so since the ring is vaginal and only needs to "treat" that area to be effective, it is a lower dose of hormone. She has tolerated it well and it is very convenient -- like the other post says put it in for 3 weeks and forget about it... take it out for the 4th week
