Why am I experiencing vaginal pain?

I found out yesterday that I had strep throat. I noticed last night that my vagina was in pain. It was red, swollen, had white spots, and would bleed when I went to wipe. My period had passed, and I have never had sex. I'm currently 17. I'm too afraid to tell anyone, especially my mom. Please help :(

There is nothing bad about developing medical issues. Never, never be too afraid to tell your mom or a doctor about medical problems you're having. If you should have an infection of some kind, it could get much worse. Talk to your mom.
