blood in stool

For the last 3 weeks i have been having alot of blood in my stool, there is alot of blood I dont mean like few drops, I mean it covers the bottom of the toilet bowl, and soaks through toilet paper, it is very dark red and kinda spotted looking. I have been having alot of severe cramping in the upper part of my stomach.This happens every time I make a bowl movement. What do you think could be causing this?

It could be just a hemorrhoid that is busting if you are constipated or your stools are very large or hard.  I suffer from that problem myself.  If the blood is actually in the stool and coming from your insides that's another story.  MY suggestion is to see a Dr.
