For the sake of hyperpreg, I wonder how one calculates belly weight VS the character's strength stat to determine when immobility sets in? Like... is it standard encumbrance rules? Does a pregnant womb count as inventory cargo? How pregnant is TOO pregnant when determining if you can still get around? And, of course, can it be alleviated with some kind of levitation spells? I dunno, food for thought.
Il need to do some digging but there might be something in the hombrew rules, i can safely say that there are no official rules i know of for this.
I would rule it 2 ways blindly, 1st every trimester -1 to the dex mod of the carachter. 2nd each baby per trimester counts as additional 20 pounds of carry weight and movement speed is quartered every trimester.
Though given the broad span of possible partner sizes we need to abridge this further based on differing factors. All in all i like this.
