Does anyone know if nuvaring is safe for women who have had high risk hpv and cellular changes, 2 Leeps, etc.?

Has it even been out long enough to test that?

I've heard great things about it, but I'm kinda worried about havin' all those hormones right up on my cervix. So I just don't know. I have all sorts of side affects from the pill i.e., no sex drive, moodiness, crying, etc. And this is supposed to help since its not in your bloodstream. My doctor didn't seem too concerned about it, but I am not so sure. I wouldn't want to find out in 5 years that I really screwed myself up.

Anybody got any info?
