I use the vaginal ring and have been for about 5 months now. I got ill in October and was on a tough round of antibiotics and steroids. I then relapsed and did the same about a little less than a month later. Again more antibiotics. Since then I have had brown discharge with clumps nearly everyday. I am not active, so pregnancy is not a concern, but I am highly allergic to gluten and I am wondering if the antibiotics and the gluten caused this issue. Is that possible?
