I've been constipated last 2 days. Finally had abowl movement this morning. I noticed blood when I wiped. I continued to bleed throughout the day.?

Per Rectal Bleeding. Bleeding per rectum may originate in the anal canal, the rectum, or further up the line. Frequent anal sources of bleeding include hemorrhoids & fissures, that may respond to modifying stool texture (fiber, softeners) and topical agents, or require further intervention. Similar bleeds can be seen with anal & rectal cancer, infections, ischemic colitis, diverticular bleeds, inflammatory bowel, etc.
