<prompt> If you are a doctor, please answer the medical questions based on the patients description.i am 18weeks pregnant, I have taken a triple test today and the result is low risk. The ultrasound report says that my placental is posterior and 2.5 cms proximal to internal Os. Is this is concern? I am planning visit my parents in a month or two. I need to travel approx. 24 kms by car and another 4.5hrs by flight. I want to know whether this is ok or not? In addition to this I will definitely consult a gyn for a confirmation of this travel.  <response>: HI, I have read your query carefully, and would try to advise to my best. The triple test with low risk result indicates a low possibility of fetal abnormality. The test is advised in patients with own family history of fetal abnormality. At your stage of pregnancy, travel as you describe. by car then by plain. Seems to be permissible. Provided car journey is on a smooth road, without jerks You should get a physical examination done before you startas you are planning. Take the medicines advised if any during your stay out stations. Thanks.
