Update at 3pm Pacific: We're admitted and starting the process going.
Because I'm not in active labor (no regular contractions), they're treating it like premature rupture of membranes, meaning they have to induce via pitocen, which is a bit of a bummer. I'm still hoping to avoid an epidural but I'm happy to play things by ear.
Right now everything is "hurry up and wait"; I've got the IV in and am waiting for my antibiotics (I had the group B swab done on Tues but the results aren't back). We'll start the pitocen within the next half hour or so.
I'm a bit freaked out but am trying to hold it together.

Hubby ran home for his toiletries and the carseat (hahah, leave it to us to forget the carseat) and I'm sure I'll feel better once he's back. Though the docs say it'll be hours and hours and hours yet before the main event.
Will update again once there's anything of note.
