How much blood? It could be anything from as minor to hemmerhoids or something as serious as colon cancer. Is the blood dripping into the toilet? Is it on the outside of your bowel movement? Is it alot or is it just a little spot on the toilet paper when you wipe?
It is dripping out and most of the times it is a lot.
If its bright blood its comming from the rectum dark brownish blood is from inside and needs to be checked out ASAP
