My son is 18 years old and eats a pretty clean diet. He is vegan, but not too hard core on tons of raw vegetables. he went to have a BM and was concerned about the bright red globs of blood floating in the water along with some undigested greens. At first I wasn't sure if it was blood because it was so bright and clumped together, but he hasn't eaten anything bright red in the last few days and they were begging to stream blood from them the longer they floated there. Any thoughts would be helpful
