At some point, every pregnant woman wonders if it is safe to travel. The American College of Obstetrics and Gynecology (ACOG) suggests that the best time to travel is between the 14th and 28th weeks of pregnancy, or the second trimester. The mother-to-be is usually over her morning sickness and tiredness by then. It is also the time during the pregnancy when complications are least likely to occur. However, it is possible to be safe while traveling during the 34th week of pregnancy. Significance Traveling at week 34 and beyond is especially risky because it is very close to the motherâs due date--only six weeks away.
When to travel in pregnancy. Some women prefer not to travel in the first 12 weeks of pregnancy because of nausea and feeling very tired during these early stages. The risk of miscarriage is also higher in the first three months, whether you're travelling or not.Travelling in the final months of pregnancy can be tiring and uncomfortable.So, many women find the best time to travel or take a holiday is in mid-pregnancy, between four and six months.fter week 28 of pregnancy, the airline may ask for a letter from your doctor or midwife confirming your due date, and that you aren't at risk of complications.
