hi, I'm 14, and i got my period a few days ago. i was doing gymnastics yesterday and when i sat on the bar, i felt pain on my labia. I left it, overnight, thinking i must have sat weirdly but when i checked in the mirror one side of my labia was swollen. So i squeezed it and it squirted pus (gross!!) i have no idea what to do, its painful (but not extremely bad) i had a shower and clean it, no more pus comes out but I'm really scared, what do i do?
