Pregnant & In the Military

Lauren • You get what you give.
What advice can you guys offer me. I just found out I'm pregnant last Saturday and my husband and I are thrilled....but he's leaving for BT and AIT October 6th and won't be back for 16wks. 
How have you guys handled pregnancy while your SO was away?
Will we likely be moving right after he gets back? 
And if so..
How do I choose an OB if I'm moving halfway through my pregnancy??
Any advice helps! Sorry to ask so many questions!
