I've been on Nuvaring for almost a year, and I absolutely love it! I had been on more than 5 kinds of bc pills in 4 years when I finally switched. My period was never regular, and it always lasted more than a week, with at least a week of severe cramping. In the first month of being on Nuvaring, there was noticably less cramping, and my period only lasted 3 (light-medium) days. Since the first month, my period has come every 28 days, and I can almost pinpoint the exact time it will start. If I have any cramping at all, it's very minor and doesn't require more than two Ibuprofen. Nuvaring has made my life so much easier, and it's so easy to use and so hard to forget. The only side effect I've noticed is an increase in vaginal discharge, and even that isn't unbearable.
