well you can poop in the middle of labor everything is pretty much squeezing down in that one area as you get closer so I wouldn't put it past to have diarrhea before labor and really could mean you won't poop in labor! lol

Yup i had it like a week before i went into labor after all the diarrhea and vomiting feeling i got constipated and didnt poop for two days then went into labor

I've heard but it wasn't true for me.

well it just started today but ive been having diarrhea and feeling like i want to vomit ill be 36 weeks tomorrow

vomiting*
