Google "hyena birth"... I do not recommend doing this at work, or during lunch.
Not only that. No other animal menstruates quite like humans do either; there's been an arms race between the placenta and the womb, and rather than a safe place to protect the fetus, the womb is more of a safe place to isolate the fetus and manage its access to the mother's resources while keeping the mother safe.
Human pregnancy is messed up beyond the obvious issue of squeezing our large brain through out narrow running hips.

I don't see anything human-specific here, this would have been true for all placental animals no?
It doesn't sound inherently human-specific, but somehow it is. Well, other primates have it to a lesser extent, but other placental mammals don't, and we have it worse than other primates. Why only primates have this arms race between placenta and womb, and why humans have it worse than any primate, I don't know. But it's definitely a thing. It's the reason why humans menstruate while non-primate mammals don't.
Interesting, I did some more digging and found this for anyone interested in a nice paper:

Yeah, a baby is literally a parasite. Fortunately it's quite easy for women to avoid accidental pregnancy these days.

In light of current energy crisis and other considerations, I implore you to consider the following proposal.
Do they? As far as I was aware, humans have a uniquely awkward childbirth due to our cranial size.
