Acne... but in somewhere unusual

Khayle
So im 13 and I've had acne about a few months after i started my period when i was 10. I had it all over my face, I now have it on my back and shoulders but also somewhere that I feel as if it is unusual. A few weeks ago, I scrached down there bc it was ichy and i felt something kinda pop and it was like puss from a pimple but gooey. And then just tonight i noticed that there was another pimple type thing new my vagina, which again popped. Is this unusual because im worried that it its and that it might mean something bad...
