Yeast infection??

So tmi post so beware— i had sex last Monday and Wednesday. But today I woke up itching and I looked and I had like white skin around my vagina and what not. I took a bath and cleaned myself. And it’s not as bad but there’s still white skin or whatever it is around the top part of my vagina ect. My labia is extremely sore and swollen. Is this a yeast infection?? I know it’s definitley not an STD the guy is clean. So I’m guessing it’s a yeast infection??
