Flying while pregnant ✈️

Now I know airlines do not allow women to fly closer to their due date. I'm going to be at 6 weeks pregant, on a 12 hour flight overseas. I'll try to drink extra h20. Has anyone else gone through early pregnancy flights? I know most women wait until after 3 months to fly but I don't really have a choice!
