It’s ok to travel
Yes safe. I traveled 5 hours by plane when i was 13 weeks pregnant.
It's fine! Have fun!
Best to inform your gynae as they can prescribe some meds to standby in case there's complications like spotting etc. 1st trimester i went Bangkok and I was given some duphaston and anti nausea pills to standby. Nearing end of 2nd trimester I went Langkawi and got meds and doc letter just in case. Also try to make sure u get proper travel insurance which cover maternity just to be safe. I think both trips we bought aviva as they cover preg related complications. Hope this helps!
