Stitch knot stuck under my skin. help!

Hello! I am 4 weeks postpartum and got an episiotomy, I received quite a few stitches and they have been all healing ok. well anyway I had one stitch that was in the middle of my vagina to far up it ended up ripping so I thought I'd try and pull it out.. me being a damn idiot I pulled the knot into my skin, it hurts sooooooo incredibly bad. I've tried to pull it through but it just won't go. I can't walk, sit, lay down or anything without being in unbearable pain. Is there anyway I can get that knot out? I have a doctor's appointment on may.2nd but I can't wait that long.😣😣 please anyone help?
