Yeast is possible, can't say what it is because it can be many things.
Ok I'm goingvto clinic but you know thus git sure? Are you a doctor? Any idea what kind if infection a vaginal could transfer? Maybe yeast infection. It does feel a little irritated the last week, but no breakout.
STD symptoms are not itchy and do not come on the next morning.
Why not an std, must be some kind of infection
No STD. See a Dr if concerned.
