I ve been on the Nuvaring for 2 years now. I used to have UTI when I started to have sex, but I ve rarely gotten it since then. In the past month, I keep on getting UTI after having sex. Today while peeing, I noticed that I was also peeing blood. I m not on my nuvaring free week, so I m not on my period. I ve heard that being on the nuvaring can cause spotting, which is normal, but in the 2 years that I ve used the ring, I have not had any spotting. What should I do?
