I have been tested for a uti like this summer and they said I didn't have one. So I thought wow okay. I know I don't have any std because I never have unprotected sex and this has happened before I was sexually active. It feels more like my vaginal area is burning And my stomach feels weird. I'm in so much pain. I feel like it's because I have a sensitive bladder and if I don't get the bad stuff out it burns very bad. Has this ever happened to anyone should I go to the doctor?
