Relocating to another state while pregnant??

Stizzle

There's been some buzz throughout DH's company about expansion into new markets.  The rumor is that they have him in mind for a position (2 promotions up) when they open in Colorado (we're in AZ now).  Within the past few weeks there has been more and more talk about it from people higher up, so we're starting to think it might really happen.  Just yesterday two different people mentioned that they might want the new hires moved by MARCH.  I'm kind of freaking out.  They don't plan on making any formal job postings or offers until Jan/Feb, so we won't know anything until then.  I'm excited for the opportunitiy and I know that if it does happen, everything will work itself out but I'm freaked out at the idea of changing OB's halfway through my pregnancy and trying to sell our house and buy a new one and especially about having a newborn in a new city where I don't have any friends.  (I did this with DD and it was NOT fun) 

Does anybody have experience with a huge move while pregnant??
