I started using the nuvaring 2 months ago, and just recently got a yeast infection. I'm not sure if it's from the nuvaring though, because I was on Augmentin for an ear infection as well. Anyways, I have gained about 5 pounds while on it and have had quite a few mood swings. I've also noticed that I have been a little depressed lately. I'm supposed to take it out on Thursday and I think I will just quit altogether.
