My poop is reddish black spots ?

Fecal color: Is most often indicative of the diet you ate recently. try to think if you ate any colored food(s) that may have caused those colors, etc. Red/Black may also signify blood in your stool, so if this persists, it is important to see your dr. and be tested for possible blood in your stool.

Likely blood: This is likely blood in your stool. I would recommend seeing your healthcare provider for further evaluation. It might be something simple such as hemorrhoids, but you might also need further evaluation such as lab tests and a colonoscopy or upper endoscopy.
