I was on the NuvaRing for about 6 months. When I first switched from the pills to the ring I was completely very happy. After about two months I experienced the same kinds of things previously mentioned: weight gain, depression, no sex drive, headaches, and getting hot/sweaty during the night. In addition to this my periods changed. I started have bad cramps again and passing large clots (which I had never done before). My periods starting being longer and heavier. I talked to the doctor and went off the NuvaRing.
Since then I still experience problems. My cycle became very unregular which was not surprising at first but after about 4 months my doctor was starting to become concerned. I would have a period for two weeks and then start again after anywhere from a week in a half to three weeks. On November 10th I started my period and it did not stop until the doctor put me back on the pill after Christmas. This weekend I had another horrible period, massive clots, extremely heavy and so much cramping I could not move and ended up throwing up. My OB is very concerned about the changes the NuvaRing took on me.
If you are thinking of using the NuvaRing, please read up on all the side effects and talk with your doctor. Make sure you understand the risks. I never had any issues other than some slight weight gain when on was on the pills. My periods became light and shorter. Since I started as a teen I have always been very regular, but had lots of cramping and pain during my first couple days. At this point I miss those days and seriously wish I would have never used the NuvaRing.
