I suggest calling your doc first and explain what's happening. If you can avoid spending a few hours in the ER waiting room and the subsequent anal probe, I think it's worth it to call and ask for advice first.
I only say this because I recently spent a very miserable night in a very miserable Brooklyn ER with a friend who was having lots of diarrhea and blood and the doc just told her to wait it out and let her body rid itself of the badness and essentially fix itself. Ugh.
I hope you feel better soon, whatever you decide to do.
