Warning: blood.

I just finished exercising a few minutes ago and towards the end I felt a tiny sharp sting near my vagina. On further inspection, it turned out to be a bump and, me being me, I squeezed it and to my complete shock and horror, blood started coming out. I rushed to the bathroom and continued to squeeze at it and on one particularly hard squeeze I actually felt it coming out (below).

Well I figured I was probably halfway through so I continued and as I was nearing the end got this (below).

Why would I have a bump with just blood? And why so much? I'm literally shaking praying it's nothing serious. It wasn't painful at all aside from the tiny sting that let me know it was there and never hurt while I was squeezing. I'm 19 soon to be 20 at the end of the year if that helps any and I've also only been with my fiancé and before me the last person my fiancé was with was eight years ago and he's been tested and is clean so it can't be an STD. I'm hoping it was just an irritated bump from where I shaved🤞🏻
