Myth: Pregnant women shouldn't fly

As long as the cabin is pressurized, flying will not harm your baby - at any stage of pregnancy. But most airlines limit travel in the last month because they fear pregnant women will go into labor on the airplane, according to Dr. Bohn.

If you do fly, Dr. Bohn says, "Walk up and down the aisles at regular intervals - at least every two hours - to help decrease the risk of blood clots in your legs, which can occur when anyone, pregnant or not, sits for too long."
