Im 33 weeks pregnant and i was wonder if its safe for me to fly. whats the worse that can happen?

Yes: Definitely safe at 33 weeks. Always a good idea to take a copy of your medical record in case something were to happen. Also drink a lot of water pre and during flight. Lastly, make sure you get up and walk around, assuming you can per pilots, to help prevent a blood clot. I recommend compression stockings as they help prevent pooling and edema in your legs when flying as well.
