I've been on the Nuvaring for about two years. As scheduled, I put a Nuvaring in about two months ago and then went to sleep. I woke up the next morning in terrible pain and could hardly pee. I took out the Nuvaring and went to my gyno where I found out I had a bacterial infection which was causing extreme discomfort. I put the Nuvaring that I had taken out back in the package and in the refrigerator. I had another Nuvaring, which I used last month after the bacterial infection was treated. So this morning, I went to go get the Nuvaring I had used for 7 hours and then couldn't decide if it was safe or effective to use. I have more on hand, but I hate to waste one since they are not cheap. Should I still use it or should I just toss it?
