I was using the Nuvaring for about six months and It started to make my vagina sore, so I took it out for about two months. After my second period ending without having it in, I put in a new one; it has been two weeks and I am potting and getting terrible cramps. I don't know what is really going on and it concerns me because every symptom list I have looked at claims they are pregnancy symptoms or ovarian cancer. ah!
