Thanks for posting your concern regarding the precautions while travelling. Generally, travelling does not cause a concern throughout most of your pregnancy. However, Even though you seem to be not having morning sickness, but pregnancy can increase your sensitivity to motion sickness, take care in case if your nausea or vomiting during take off and landing of your flight. You should not travel after your seventh month Take along something to drink try not to get cramped into one position for a long time Be familiar with potentially harmful foods during pregnancy and drink bottled water. And of course your doctor has already prescribed Duphastan for normal maintenance of pregnancy. Wishing you a happy n safe journey, Insha Allah! Regards!
