You can track foods that you eat to see if it looks like undigested food is passing through. That can signify that you might need some digestive enzymes and overall, that there may be an imbalance in the intestinal flora.
I've known patients to pass many things out of their body through almost every orifice during the detoxification process of the candida Plan and would expect some similar results on other programs. If you pass tissues, you usually get some type of bleeding in small amounts, but that can be the body letting go of dead or diseased tissues. Your pictures didn't look like that.
