I've never had dark spots in my poop from the suppositories. My first poop after use sometimes has white in it, oily looking liquid, and lots of gas the morning after use, and gas with oily stuff expelling (I.e., always wear a panty liner strategically placed under your butt-lesson learned).
Maybe the black is blood, like you suggested, and unrelated to the suppository.
