The doctors room has a machine but the quality is not good. It is enough to check the size and heartbeat of your baby. You will also go to the Antenatal Monitoring Centre (AMC) twice - once around weeks 10 to 12 for First Trimester Screening and second one around week 20 for Detailed Scan. AMC scan is much clearer.
My scan was done at AMC & ADC during first & second trimester (monthly appt). However 32 weeks onwards, my scan was done inside my gynae's room-scan wasn't so clear.
