Help please !!! Yeast infection

Okay so I’ve had unprotected sex last Saturday and he ejaculated inside of me after we went to sleep days after that I was perfectly fine until yesterday I felt slightly dryness and burning while in the shower and today it kind of got worse the burning discomfort and itching we had sex yesterday and I’m scared I’m might have a yeast infection and could possibly give it to him !! I have little to no discharge but when I looked it’s like little white separated discharge
