Traveling 3rd trimester.

Kristin
What are your ladies thoughts. I travel almost daily for my job. Often times 2 to 3 hours in one direction. I'll be 31 weeks tomorrow. I'm scared Ill be on the road several hours from home, if I should happen to go into early labor. Praying I make it to mid March at least! What do you think is a safe distance range to stay in?
