My entire family (7 of us) passed around some stomach bug that left our stools pale in color. Off white ish. They were also very slimy. That lasted for a couple days and then other changes. The entire stomach , weird poop, cycle lasted a couple weeks.
Strange, I know. I worried because I have Crohn's, but when all of my family had the same thing happen, I figured it must be a bug.
Hope you get to the bottom of it.
