This may sound dumb, but how do you know if it is internal bleeding or not in your stool? I am newly diagnosed with Crohns. My diarrhea has stopped (I think I might be constipated) and am back to solid stool. I have been having a ton of pain and symptoms, and today noticed that even though I had solid stool the water in the toilet was dark mahogany/brown at the bottom where I couldn’t see the bottom of the bowl, but the top of the water was clear. There also appeared to be black specks in my stool. Is this bleeding? Should I be concerned? I’m not dizzy or anything.
