Pregnancy and travel...

Hiyaaa lovelies....I'm new here although ive been on this app few years back ive only just started using this again... im currently 9 weeks pregnant and thinking to travel to mexico however i know now would be too risky... if someone could please let me know at what week exactly is considered most safe to travel?? To the mums out there n fellow soon to be mums at what week did you travel?? And would a history of miscarriages dictate weather or not i can travel???
