I do agree but a little advice for u in first trimester you will easily get tired coz ur body is working overtime these days so you will have to take extra care sothat you dot feel extremely tired.
this would generally be ok, as long as you havent experienced any bleeding so far, its generally fine to carry on as usual. If in the event you were to miscarry there isnt anything that they could do to prevent it and it wouldnt be caused due to you travelling etc, just take time to rest when you can
