I had protected sex with a guy. He did oral on me without protection. One day later my period came. Two days later, I started with a foul smell (it’s not fishy but it’s bad) and discharge and I still have it. Could it be gonorrhea or is it BV? He said he doesn’t have any oral symptom. We used condoms but we shared his towel and I slept naked in his bed sheets, I don’t know if there was any fluid from him and I touched it and then touched myself or something like that. I also had COVID around 3 weeks ago and my immune system isn’t the best right now. I once had tonsillitis followed by BV and the gynecologist said that could happen during or after an infection.

EDIT: it was BV. Went away with metronidazole cream.
