vagina question??? HELP PLEASE!!!

So for the past two days this weird pimple like bump showed up on my vagina and it’s kind of a firm if you touch it it feels like a little ball, I was wondering if anyone could please tell me what it is?? I have never been sexually active before in my life so I don’t know how I got it BBC and I have no clue I’m too scared to go see my doctor in fear of being embarrassed. I was wondering anyone please tell me what it is because I’m freaking out😰😰😰
