birth control
"I find the Nuvaring  to be very effective.  I had tried a variety of different pills, but I experienced terrible mood swings on most.  I like the Nuvaring because it does not cause me to experience  those  mood  swings, I have lighter and shorter periods and it is convenient  not to have to take a pill everyday.  The only con I've experienced is that it can sometimes come out during sex or be bothersome to my partner during sex.  I would recommend this if you are having difficulty with pills and are not ready to try an IUD."
