Hallow Dear, For normal pregnancy mothers, traveling between 14 weeks to 28 weeks of pregnancy can be permitted. However, you have low cervix which is some what shorter in length for which you are on some medications. I believe, these medicines are to quieten your uterus which might have been irritable. With this risk factor, travelling for more than 8 hours would be rather tedious. Though actual time in carriages is five and half hours, home to airport, boarding time, landing time, all these have to be considered. So total traveling time would be definitely around 8 hours or so. Air flight may be smooth; however, uphill road journey for three and half hours might be strenuous for your uterus. Please consult your Obstetrician. He/she have clinically examined you. If according to him/her, it is safe to travel, you may; however, from your history, I feel you should avoid travel, deliver in Mumbai and then go to the mother s place after delivery. Whenever there is any risk, we always advise to deliver at well equipped hospital. Then why should you travel from place like Mumbai to some other place? In India, Mumbai is one of the cities where the best Medical treatment and facilities are available. I hope you will take informed decision. Dr. Nishikant Shrotri
