My Bowel Movements Are Black Why Are My Bowel Movements Black? Should I Be Concerned?

Why are my bowel movements black? Should I be concerned? - my bowel movements are black

I agree with the flu or something a bit like the flu feels ill (which is probably the neighbors, most of my friends and I had one time or another over the past two weeks). I am currently prescribed the antidepressant Remeron, and Monday, I got my dose of 7.5 mg to 15th I also took ibuprofen and acetaminophen (one or the other, not both) in these days stick to the mouth. I am also on my period. Tonight I had a very uncomfortable chair was black and a little bloody. I did not get the Pepto Bismol or black anything to my chair. Why is it black? What is fever? Should I see a doctor?
