I recently took antibiotics for streap throat. Since then i have experienced burning inside the vagina, not when I urinate. Itching of the vaginal walls, redness, burning, but it expecially burns when my boyfriend cums inside of me. I go to the gyne on a regular basis for check ups and paps and everything is good. I'm just not sure what is going on? I have to pee a lot also not emensly but more than normal. I am also on Yaz birth control and periods are normal. Do you think I have a uti?
