So, thanks to whoever suggested twins on here yesterday (and elsewhere). Yes, I'm glaring at you now.
I dreamt about them last night. I dreamt I had a boy and a girl, and it was utterly panic inducing. It was SO vivid and weird.
Even though I seriously doubt it, it will now be in the back of my mind until the u/s. We have little family history on the maternal side (DH's mom is a twin). While the numbers are in the possible range, they are on the low end. I think the odds are pretty slim to begin with.
Oh, and holy shit, that would be awful. There are days I'm not sure we can afford ONE baby. Two makes me shiver in a not good way.
