Generally speaking, the safest time for a pregnant woman to travel is during her second trimester, provided she isn't experiencing any complications. If you are pregnant and considering travel, you must consult with your doctor, especially if your pregnancy is high-risk. Take into consideration the standard of medical care at your chosen destination, just in case you need help. Some countries have reciprocal health care arrangements - check with Medicare. Travelling to developing nations is never a good idea during pregnancy for various reasons, including the risk of disease and the comparatively low standard of medical facilities.
Pregnant women experiencing complications are advised not to travel. Some of these complications include:
Cervical problems, such as 'incompetent cervix'
If you are aged 35 years or over and pregnant for the first time
Gestational diabetes, past or present
High blood pressure, past or present
Pre-eclampsia, past or present
Abnormalities of the placenta, past or present
Prior ectopic pregnancy
Prior premature labour.
