Roundtrip travel by flight that lasts 1 hour in precise!

My wife is pregnant, will be 5 weeks+ this weekend and we are taking off to nearby destination which lasts about 1 hour flight and return by Tuesday( 6 weeks by then) by flight again which lasts for on hour. We are just going to relax at a beach resort for 3 days as whole which may not have connected travel further, except for airport transfers by car.

asked our doctor, she was okay with it and told us to be careful during travel. And I assume ours was normal pregnancy and didn't have much complications rather.

But there is mixed reactions over taking a flight during first trimester. Please send me your suggestions, like if someone has really done that in past. Am little skeptical and confused.
