Traveling while pregnant

I am 29, first pregnancy and currently 31 weeks. So far, has been an uncomplicated pregnancy. My man and his family want to go to bora bora in two weeks (which I’ll be 33 weeks) for about 4 days. My doctor has said she expects me to go to term. I do not have any past medical history, so no hypertension or diabetes and no gestational diabetes either. We live in central FL, and the flight says it’s like 17 hours, which I assume includes time change. So maybe about 10 hours of real fly-time. I sent a message to my doctor about getting a clearance letter for airlines, and still waiting to hear back but just wondering if anyone else with presumably “uncomplicated pregnancy” has traveled internationally, and if so, what that was like? I know it’s a “go at your own risk” kinda thing, just wondering what anyone else’s experience has been, if they have done it.
