Long ago when I was young, single and already had a plan for the future, I was in a position of uncertainty about my job for the better part of a year, and remembering how INCREDIBLY stressful that was, I can only imagine how much worse it must be for someone farther along in her life and career. 
I agree that the more you can do to feel in control - start the job search now, have a plan for what you'll cut back on first if either or both of you do become unemployed - the better you'll feel.
Hang in there. I'll keep you and your DH in my prayers.
