Internals didn't hurt. Just be sure to relax when they do it. If you're tense, then it will hurt.

As for pooing.. my body cleaned itself out well and truly with a day & a half of diarhea before labour. Try not to have a fear of pooing.. because pushing that baby out feels exactly like doing a great big poo up until the end, and you don't want to be 'holding it in' for fear of pooing. The body is pretty clever, and often cleans itself out before or during the early stages. But it doesn't surprise me at all that it can still happen
