Hello, I Had Sex Friday With My Boyfriend, He Was

Hello, i had sex friday with my boyfriend, he was really rough and at the time it didnt bother me until today i noticed a pink bulge sticking out of my skin, its right above my vaginal opening but not coming out of my vagina. I touched it while showering and it was tender and sore. It didnt hurt though. I dont have any sti because i been tested for everything. I have an appointment on thursday but i would really like to know my options before hand.
