Yesterday, around 7:00 P.M. I used the restroom, and there was blood in my stool. I m not talking a little bit of blood either. The entire toilet was filled with dark maroon colored blood. I know it s gross, and I m pretty embarrassed about it, but I m also terrified at the same time. It wasn t a one time thing either; it continued on. It happened around 1:00 A.M. last night, then at 7:00 A.M., and again around noon today. It is 9:40 P.M. and it happened yet again. This time, I noticed bloody pink and red tissue attached to my waste. It s very alarming. I know I do not have external hemorrhoids. I ve checked. I believe the problem is internal. Please help.
