Wisdom teeth extracted- risk for dry socket?

I had my wisdom teeth out on Friday (fairly straightforward procedure, all 4, no stitches). I've been as careful as I could to avoid anything that might even possibly put me at slightly higher risk of getting dry socket (basically been on an all liquid-puddingish diet since getting them out, no harsh spitting, no straws, no strong swishing). Tonight when I closed my mouth at one point, I felt something squish a tiny bit between my back molars. It seems that something pinkish gray that was resting on top of the extraction site (bottom right) is loosening. I am pretty nervous that this is the blood clot, and that I am going to be in bad pain really soon. Any dental experts out there have any advice for me? After it moved, I had a tiny bit of bleeding. Now that it's loose, I don't know if I can avoid it with my teeth, and I'm afraid of ripping the whole thing off. So what's the deal; should I be worried, or not? In case this helps, that tooth had a tiny flap of gum over it to begin with and this area was being treated for an infection when I had the teeth out. Could that be the little flap instead of the clot...? Any serious info would be helpful.
