Could it be something you ate? The first time I ate raspberries I saw red later on and I was shocked, until I remembered the raspberries. Same with blueberries (comes out BLUE!), or tomato skin, and especially when I eat beets. Maybe keep a simple food diary to track your output.
Thanks for your reply! I have a loop ileostomy right now so all my output goes there. I’ve only had mucus come from the jpouch. What was in the mucus definitely looked like a little blood. Not much. It was very light colored. I’m pretty sure it wasn’t any food that bypassed the ileostomy, but I could be wrong? I didn’t eat any rough fruit or anything. A food diary is a good idea tho!
