I took 2 vacations this pregnancy, the first I was between 20 and 25 weeks and the 2nd I was around 30 weeks or so. I've been on bed rest since 8 weeks but still was given the okay to go with restrictions, the flight was about 2 hours so not very long. My doctor just told me I had to drink a bottle of water BEFORE the flight (I can't remember what the purpose was) and told me to get up at least once during the flight. I had no issues flying the biggest a issue was the TSA check because I didn't want to go through the metal detector machine so I had to do a pat down (it was super easy though). During take off on both flights the baby started kicking a lot and I felt a lot of pressure in my stomach which felt a little funny but that was all. I also felt a bit nauseas but I brought along some trail mix and after eating a little I felt fine. Have fun on your trip :)
It should be fine bjt you should check with your dr to make as everyones case is different
I flied safely..... and my baby is fine......
My doctor give the go ahead to fly until 32 weeks.
