I'm 10weeks pregnant by iui.when is it safe to make international travel plans?flight duration is 22hrs excluding transit.re says no,not met obgyn yet

Why not trust him?: There is no evidence at all that international travel by any means is a risk for a 10 week pregnancy. However, your RE no doubt has his/her reasons, and they may be based on specific knowledge of you(r case.) I suggest you not sample many doctors and "take an average" of the responses: if you trust you doctor(s), and I hope you do, you should likely take their advice. I do hope this helps.
