BV or STI? Help I’m panicking

[Countrymumma91]

This is so embarrassing but I slept with a new partner on Thursday unprotected. Ever since I have noticed I have a lot of thin discharge that’s yellow and can feel it coming out (so sorry for the TMI). I can’t imagine an STI showing symptoms the next day (again tmi I originally thought it may be his fluid 🙈 but it’s not stopped) what could it be? I will obviously get myself checked but feel as if symptoms of an STI wouldn’t show in a day?

I've never had bv but have been told it has a distinctive smell?
Sometimes my thrush has been yellowy discharge as well as the standard cottage cheese style stuff so could well be that? Imbalance from a new partner. I'm with you I think an sti takes about 2 weeks to show.
I would get one of those thrush bv test strips from boots and an sti test just to be sure 🙂 is it itchy?

Bv is pretty distinctive by its smell. Get yourself some boric acid suppositories.
