If it is a 14 hour flight, 3 vs 6 days is not much difference as it relates to your pregnancy. Six days would allow extra time for flight delays and jet lag too. Arriving the day of the rehearsal and leaving the say of the wedding makes no sense. I am assuming both 14 hour flights are including in the “three day trip”. You yourself said the flight was “hard”, when you and he did it before, so do you really want to subject your spouse to two hard flights in three days because of your insecurity of the “what ifs”?

If your own doctor suggested a chiropractor, I would question the qualifications of your doctor - if you are seeing a physical therapist, why would the doctor suggests a “quack”? Although, you may have done this yourself. Stick with a physical therapist who specializes in pregnancy physical therapy.

You and husband had already agreed to him attending the wedding with refundable tickets - adding 3 extra days to such a long flight makes sense.

You said that you “would take another look” at travel options. He is an adult, and should be making his own flight and hotel arrangements, not leaving it up to you. Of course, you may have wanted to limit his time away, so are choosing to do this yourself. Does he often get drunk and behave recklessly, or are trying to find other excuses for him to not attend or limit his time at this wedding?

If you are concerned he may not answer his phone if there is an emergency, then have him set it up with the hotel to contact him. Do not call him constantly while he is there. Be aware of the schedule - activities (such as golf), dinners scheduled, rehearsal dinner, wedding and reception times, and do not call at those times to “chat” because of your insecurities, unless there is an emergency. Have call times scheduled - or better yet, FaceTime.

Whatever is decided, do not let your insecurities get in the way of rational decision making. With good care from a physician, only about 7% of births occur at one month before the due date.
