The second trimester is usually the best time to travel. Your morning sickness and initial exhaustion from the first trimester have usually reduced by now. The last trimester is too risky, as your doctor would rather you be as close to home as possible. Here are some tips for traveling while you're pregnant!
Stretch as often as you can.
Wear loose-fitting clothing.
Drink plenty of water.
Prepare for nausea as flying and driving can trigger it.
Keep snacks on standby.
