is it a bad idea to plan a trip to Cancun when 4 weeks pregnant ?

UPDATE: Decided it was a bad idea after all and we will be headed to Disneyland instead 😊. Thanks to those that
Commented for their advice !! 
We just found out I am pregnant and want to take advantage that I am on summer vacation . We are planning to go in two weeks so I would be about ) weeks pregnant . I just don't know if I should because I don't want to feel sick while I'm there . So far I have no nausea or symptoms !!Â
