I am looking for a place to do Obstetric ultrasonography (as I understand in Thailand it is called 4D ultrasound) for the period of about 15 weeks pregnancy. In my home country women in their 15-16 week undergo a thorough ultrasound checkup of the unborn baby that includes stuff like Upper and lower limbs, spine, abdominal cavity (kidneys, stomach, liver, spleen, bladder, umbilical cord), chest (heart and lungs), neck, facial structure, skull and brain. Every place I talk with in Thailand say they do it only in the 18-22 weeks or more. For 15 weeks they only suggest doing a normal quick ultrasound that checks checks stuff like legs, hands and heartbeat. Some places say they can perform the thorough checkup earlier but never do. My issue with it is that I think that if a place is not doing it regularly they wont be able to fully understand if everything is ok because it is not their expertise. Did anyone ever do this checkup in Thailand in 15-16 weeks preferably in Bangkok area? Can you recommend a place? Also, any other information about this subject in Thailand will be appreciated. Thanks
