I got a bright red blood spot on the surface of the stool. I passed two sausage like stool. Only one stool has a blood spot on it. It was like a 1 cm long ( guess). The stool color was brown as normal. Blood did not dissolve in the toilet and there was no blood on the tissue, after wipe. This is the first time, I have seen it. I hope it is not serious. I am only 36.
