The fetal position is fine. Avoid sleeping on your belly, but sleeping on the sides and back is fine too. As far as I’m aware, leg positioning is mostly to your tastes aside from that both of them should have the same position; don’t have one outstretched and the other tucked against you.
Is it bad to sleep in a hunched over or crunching or hooked kind of position?
After you are asleep you likely move soon anyway. That means you likely don’t get very far by optimizing sleeping position.

I dunno, what does a literature search tell you?
