military daddy??

Just found out last night that my bf will be going tdy when I'm at 37 weeks. For anyone who doesn't know what a tdy is, it's basically an "away meeting" so to speak. He's only going to be gone for a week but it just makes me nervous! Anybody else experiencing anything like this? Luckily, I have family in town so I've made arrangements in case they need to take me to the hospital but it's just something that I wasn't expecting so I'm nervous.
