No, not normal at all. Being a patient with UC I can tell you that if blood is bright red, it means it comes from either the colon, rectum, or anus being the latter possibly due to hemorrhoids. If stool is very dark, like almost black, the bleeding is most likely from the upper digestive system being the stomach or esophagus possibly the culprits.

Either way, I strongly suggest you go to a doctor and check what’s going on. Blood on stools is something serious that needs attention immediately.
