feels like a piece of hard plastic under my skin near vagina

It used to be a green dot, and I've felt it before but I'm not sure what it is. It's right underneath my skin near my vagina but I don't know what it is. It feels hard, and it's flat. I can legitimately grab it with two fingers. I've tried to cut it open myself (I know,not the greatest idea) but I was so bothered by it I couldn't get it out, whatever it is. This is now, after I've picked at it and whatnot. I know TMI sorry!!! But the weird thing was, there were TWO tiny holes on each side of it and I could slide a pin needle right through it without any pain. Very weird. Now there are ingrown hairs there I believe and mypanties keep bothering the bump and it hurts so bad. I'm not sure what to do. I do not have insurance at the moment:(
UPDATE: VERY TMI
Hey guys ! Thanks for everyone's input on my post. I took a very hot bath today and once I got out I always inspect my areas and I noticed the spot was BLACK. I got scared because I wasn't sure why it was black I thought it was a worm. This is why I thought it was a worm:
and then it occurred to me: it popped and it's an ingrown hair. I inspected closer and turns out it was a very thick wad of ingrown  hair. I am so relieved.  Here's what it looked like when I picked it out with a tweezer 😷😷😷
