So, I recently had a sinus infection that I had gotten meds for. Well, ive been feeling better except for a cough and sore throat, which I thought was just from coughing too much. Went back to the doctor today and found out I had strep. Here's where the strange and probably stupid part comes in. My SO and I had sex last night and I gave him oral before penetration. Would the strep cause an infection in my vagina? I know this is strange but I am an over thinker, and just worried that I might end up with some kind of infection down there. Please no rude comments because trust me I am 100 percent aware that I sound completely stupid. I tried google but had absalutly no luck.
