Yup, it is fine, I travelled during my first trimester too. I think it would be good to let your gynae know though, just in case he/she would like to prescribe any medication on standby in the event if any spotting happens when you are overseas. Cause that was what my gynae did. Hope this helps!
Yeap it would be okay. I travel during first trimester for 8 hrs flight to Perth and for 5 days 4 nights.
Yup! As long as no bleeding whatsoever, perfectly fine to travel.
