Hi, my wife is in her fourth month of pregnancy

Patient: Hi, my wife is in her fourth month of pregnancy. She has 6 exams of her final year graduation 250km away from where she is currently residing. She has to travel by train to the other city and has to stay at her sister’s place for a month to attend the examinations. We are worried if it safe enough to travel by train for 8hrs at a time and also to attend 6 exams (5days gap between each exams) again travel back to her residing city by train in 5th month of pregnancy. please advise…

Doctor:
