labor early. When I was young (and less intelligent) I drove cross country- alone- when I was around 32 weeks...because my sister was pregnant, too, and we were due a week apart, and were having a shared shower.
My insurance warned me then that if I went into labor and was more than 90 miles from home they wouldn't pay a penny! I gambled, and everything was fine.
At the time I'd never had any major medical complications or crisis (other than a bunch of broken bones...). Now, looking back, man, what an idiot I was!!!!
I would still be paying on that c-section and the NICU costs if he'd been born while I was traveling!
