See a doctor: Tarry stools can be a sign of bleeding in the gastrointestinal tract."flu" is actually a respiratory illness with fevers, sneezing and cough". This sounds very different.

Black stool: Is worrisome for gastric source of bleeing, either ulcer or tumor or gastritis especially if you didn't take peptobismol. Get it checked out promptly. Unlikely due to flu.
