The periods one is actually addressed by most creationists. In the book of Genesis, Eve (and consequently, all other women) is punished with the pain of childbirth for falling for the lies of the Serpent, and so most creationists view periods as part of that curse. Pretty messed up but that's how they see it. The vagus nerve is completely nonsensical under intelligent design but makes complete sense under evolution. The biggest issue I see is why TF God made everything in the universe look exactly like it's way older than it is. The best argument I can come up with is that it was an epic prank to totally own the libs who find all of this stuff 6,000 years later. Like God is like "Hah you just got pranked you stupid nerd! That'll teach you to be curious about all the cool shit I made!" To believe in creationism is to believe that a huge swath of scientists across an incredibly broad set of fields are part of the largest conspiracy ever conceived of to try to discredit the Bible, or that God is an evil trickster who intentionally laid this giant trap to damn countless souls to Hell.

Rabbits' digestive systems are so inefficient they have to eat their own shit to get enough nutrients.

no loving god could create the shoulder joint

It might be intelligent design but not perfect design. I mean we build stuff with flaws too and consider ourselves intelligent.

If God or some space alien was really good with biotech and had these parts laying around the result is pretty good. Most humans function for several decades before stuff breaks. The earth is also a pretty stable ecosystem.

Both much better than we could build.
