“Fell pregnant”...how quaint. How exactly does that happen?
I would presume, for starters, that they fell on their back.

Seems like if they "fell pregnant", it sounds like it started while they were still standing.

Seems that you have thought this out more thoroughly than I. Based on your conclusion it would also be logical that the further into pregnancy the fall occurs the more likely that it would be forward.
