I was using Nuvaring for about two years and I stopped using the Nuvaring almost three years ago because we decided to start our family. We have been trying to conceive to no avail. I have brown spotting before and after my period and my period itself is also brown. I noticed brown bleeding while using the Nuvaring, but I wasn't alarmed (foolish me) and neither was my doctor. I have been seeing a different doctor and I now have been diagnosed with endometritis, which is a chronic uterine infection that I believe was caused by the Nuvaring. I am now infertile and I believe it was due to the Nuvaring. If any other women have experienced infertility after using the Nuvaring please let me know!
