What dose it mean when you cant stop bleeding?
you probably have a low platelet count (a lower than avg. amount of clotting cells) like the guy before me, who wasn't much help, its all to do heamoglobins, these are the chemicals in your blood that star the clotting process, if you have a low amount of these, it will take a while for your blood to clot and scab over.
your blood hates you and is trying to escape!!!
there is a word for it... haemo somethign or other
This really depends... where are you bleeding from? Is it your period?
you might have hemophilia, but that's an extreme case.
