The second trimester (weeks 14 to 28) is widely considered the "Golden Period" and the best time to travel during pregnancy. By this stage, the morning sickness and extreme fatigue typical of the first trimester have usually subsided, and the physical discomforts of the third trimester (like back pain and frequent urination) haven't yet reached their peak. Statistically, the risk of miscarriage is lowest during the second trimester, and most women still have enough mobility to enjoy sightseeing. Travel in the first trimester is often difficult due to nausea and the risk of dehydration, while the third trimester brings a higher risk of preterm labor and more restrictive airline policies—many carriers won't allow you to fly past 36 weeks without a doctor's note.
