I'll chime in as I'm refusing to let my first pregnancy be surrounded by worry.
Wow, 12 hour shifts! Are you at least able to tell the people you work with that you're pregnant? That way they will have sympathy for you when you're dragging. I feel like, being a teacher, I need to wait until I have a contract in hand for next year first. The gown sounds beautiful! Your SIL must be handy.
Talking about the pregnancy sinking in: my sis came with me to try on a matron-of-honor dress for my best friend's August wedding. If all goes well, I'll be 8 months preggers. They had me stuff official "pretend baby" pillows under the dress. It was BIZ - ARRE!!!!! And a little nerve-wracking....like I don't wanna count my chickens kind of thing. Luckily, they said it would be ok for me to wait another month before buying it. This is it, if you like that kind of thing. Except, click on "spice" for the color. I had originally chosen a much sexier one, but with the pillows underneath the hem in front came up to my crotch. HELLOOO!!
Ok, it's time for my nap.
ps - cileag, I put you under "week six" cause that's the week you're starting. That's how I listed everybody. Please let me know if I'm wrong.
