Am I Pregnant¿?

So I recently had unprotected sex with my boyfriend (we don’t normally) but I am concerned bc it was on one of my fertile days. He pulled out but I don’t know if he did completely. Ever since I’ve had itching, burning, and frequent urination. However I think I may have an allergy to his cum because usually when I give him oral, my lips become irritated and itchy. So I’m thinking it could also be an infection. It’s been 5 days since and I’m paranoid. Please leave your thoughts!
