Answer 1

Pregnancy and childbirth are very demanding on the body.

Your centre of gravity shifts as your pregnancy develops, and you end up with a wider stance. All your joints become looser as you produce hormones like relaxin. Yes, it’s actually called that.

This allows the various hip/pelvic bones to flex/pull apart a little more during delivery, so the baby can pass through and be born.

Actually, we produce a lower amount of these hormones with every cycle as well. Women are more flexible and more likely to dislocate joints around their period.
