Hi and thank you so much for this query. I am so sorry to hear about this low lying placenta. in medicine, it is called placenta previa. The main risk associated with this is that of bleeding before delivery or difficult and impossible vaginal delivery during labour. It is okay to go about your daily activities with reservation because that is not a possible cause of bleeding. However, if bleeding should occur, then you would need to have strict bed rest as part of medical management. Have you be booked for an elective caesarean section? 4hours o traveling is no problem unless the roads are in such a terrible state that may make traveling a huge concern. I hope you find this helpful. Thank you so much for using our services and please do feel free to ask for clarifications if need be. I wish you the best of health. Dr. Ditah, MD.
