Yeast infection??

So I (20) hooked up with this guy the other day, and somehow during, the condom came off. I didn’t notice, and he says he didn’t notice (which I think is a lie, but that’s not the point)

Anyways, I didn’t know until the NEXT DAY when I went to pee and when I wiped, a condom came out of my vagina 🙃

It was there for around 30 hours.

I took a plan B, so that’s not my concern, but since then I’ve had some minor itching (nothing extreme; just enough to be uncomfortable) and a yellowish discharge.

I’ve not had a yeast infection before so idk how to tell, really.

What does this sound like to y’all?
