Grey poop?

Since my small vowel follow thru on Friday I have been having a ton (15+) relatively painless white or grey ish poops daily.
They look like cement.
There is blood as well but I think it is just visible because of the light color.
I'm assuming this is normal but I wanted to know if any of you have had this following the nasty gluey barium

Figured. Just wanted to be sure, would have been nice to be warned that this may happen
Thankfully I am continent again (got to celebrate the small stuff)
