I think somethings wrong.

So, last night me and my boyfriend had sex. it was unprotected but he pulled out and we were sure of it. Shortly after, i went to use the restroom. When i peed, it was stinging and burning like hell down there. i looked down and my vulva and clit were swollen as i’ll get out. now it’s the next morning and they’re still swollen. what should i do, i’m panicking!!
