For the past 2 or 3 days I have had dark brown(almost black) loose stool. Theres still some type of texture to it....its not watery but breaks apart real easily. It started with stomach cramps, then the cramps have almost completely stopped, but the stool is still the same. I been eating a lot more vegetables this past week....also raspberries/blueberries. I don't know what it could be.
