By 'upper stomach' you mean your actual stomach, presumably? The question you'll get asked - or should do - is how often you're going to the toilet and whether there's anything unusual about what comes out.
Also, if you're taking any pain killers don't take any without food...

Plus... if your poop looks black and tarry.. that's a sign of bleeding in your stomach... a sure sign of ulcers.
It looked like that a week ago but I was using Pepto Bismol at the time. Other than that the poop looks pretty regular.
And I use the toilet at least three times a week, so constipation is definitely not the problem.
The color change is because of the pepto.
Could it be diverticulitis maybe?
