What does it mean if you bleed longer than you usually do?

Without getting into the nitty-gritty details....if your "bleed time" is longer than the normal limits, it means there is a coagulopathy---or a problem with the clotting process. There is a multitude of reasons to why this can occur, but simply put, if you're blood takes longer to clot (ie stop the bleed) there is some sort of problem with your platelets, coagulation cascade, coagulation factors, or regulators of the coagulation system.
