birth control
"I love my Nuva ring.  I was on it a couple of years ago but had to stop because my insurance wasn't covering it 100%.  I got a mirena IUD instead.  After a year of being miserable with the IUD, I had it removed and went back to Nuva ring which my insurance is now covering again.
I haven't had any side effects that are different from regular birth control pills.  I actually have less problems because I would immediately start my period if I was even a couple of hours late taking my pill.
It is very convenient and I don't have problems with it falling out.  My partner says he can occasionally feel it during sex but that it isn't uncomfortable. 
There are risks with the NR just like with any form of birth control or with pregnancy."
