My little family (hubby and 4 year old) are flying to North America in early December, so I understand your concerns very much so. I am currently on the 2ww and have 2 embryos left after this, and plan to have one more FET before we leave. This trip for 2 months means alot to all of us (Xmas with family) so I guess it is important just to stay as relaxed as possible, drink lots of water, and get your partner to do all the lifting of luggage etc.. Also, just rest and sleep as much as you can when you get there. Eat well - fresh food.

I think there are FAR worse things to do while in the 1st trimester !! Go and have fun !
