What To Do If Had Unprotected Sex And Soreness And Whiteness Around Vagina?

Hi Friday I got drunk and slept with another guy unprotected then two days later I slept with my boyfriend of three months also unprotected. I slept with him everyday after that but about 5 days after I slept with another guy I slept with my boyfriend Tuesday and felt really sore afterwards. The lips of my vagina right before the opening and they were a bit swollen and I also noticed what looked like whiteheads around the opening and inside. They would go away after wiping a few times, but they re all down in my vagina but I m not sure if it s on my cervix
