S.L.
This is a hard one. My husband travels a lot as well. But he has somewhat control of when his trips are. I always had him not travel the two weeks before I was due. But I always go early. I have yet to make it to 39 weeks. I am only 5 feet tall and so the babies are always smooshed. My twins came at 36 weeks. That one was also a planned c-section. If I were you and he has some control I would just try to have him around at least the week before. Esp. if you are having contractions and are effacing. If not, you probably do not need to worry so much. Best wishes!
