im having a similar issue, but im currently pregnant and im pooing mostly orange/some reddish and some almost black. its weirding me out but ya know, not something i wanna tell a doc if it isnt necessary... howd this go for you?

I'm not sure if its the same thing, but awhile back we went to a friend's place for a BBQ. After that my 3 girls and I had orange poo too, with oily bubbles. Went to doctor and he said we ate something oily. Then thinking back and asking others at the BBQ what foods we ate that might have caused it, the conclusion was a bowl of spaghetti which the 4 of us ate and others didn't.
Hope this helps.
