Travel in first trimester

Booked a trip to Europe months ago but recently discovered I am pregnant. I’ll be 10w+ on departure day and flight time is ard 13-14 hrs. Gynae only mentioned 1st tri could be rather unstable but did not strictly stop me from going. So far I feel ok at 6w, just easily tired and sometimes nausea at night. I’m torn whether to proceed or postpone the trip. Any mummies here travelled in 1st tri before and can share their experience?
