I flew to Hawaii at 9 weeks. And I'm going back in June. My dr said it shouldn't be a problem.
a pregnancy is calculated as 40 weeks. which is a little over 9 months. Check with your doctor on the traveling since everyone's pregnancy is a little different. your dr may have certain restrictions for you.
