See a dermatologist if it doesn't heal in a week or if the mole was black. Keep the wound dry for several days and dressed with bactricidal cream. When it scabs rub it daily with Vitamin E squeezed from the capsules and take 1000 mg of vitamin C a day for at least a week. As everyone stated lots of bleeding is normal. It would have been nice to have saved the mole for evaluation of taken a picture of it with your digital camera. Constant pressure for several minutes will generally stop the bleeding.
Yep get it checked out ;)
moles, as well as skin tags, have tons of little blood vessels running through them, thats why they bleed so bad. I had that happen before. your best bet is to have it checked out, just to be safe
