Please read. I need answers and I can't seem to get any.?

I know this is in the wrong category but I am really not feeling well and I need advice. I had a tooth extraction done at about 4. I was fine and just about 15 minutes ago I started feeling like I was going to p out. I went to walk and started to black out and get dizzy. I am shaky now and feeling nauseous. I took tylenol. I don't know what to do because I am feeling terrible. It is still bleeding. I am really not feeling well. I am eating yogurt now but it is not making me feel any better. I am also not on any narcotic, just tylenol. Please help.
