I don't know what pregnant women did before The Googles. The search terms I have googled in conjunction with 'pregnancy' are legion, and mostly disgusting. Some of the lesser-embarrassing ones include 'pregnancy and nosebleeds' (super-common!), 'pregnancy and migraine auras' (not terribly uncommon!), 'pregnancy and losing an eyebrow' (commoner than you'd think!).
And I knew that lower back pain was a thing (because come on, these boobs. If I were my lower back I'd be a jerk about it, too), but I've been having extremely localized pain in my mid-upper right back.
'pregnancy and mid-upper back pain'...hey, that's totally a thing! Except everyone is like, Yes! I have that! And my doctor doesn't know what to do about it! So looks like we'll just have to suffer through, ladies!
And then a few of them are all, It's trapped gas, or a pinched nerve. At any rate, do X and Y to try to expand your rib cage, and that should help.
It helps. Thanks, Dr Googles.
