KKH subsidised patient - no ultrasound given at 2nd trimester

I am currently a subsidised patient under KKH. Is it normal for the doctor not to do any ultrasound from second trimester onwards? Except for the detailed scanning (at ~20th week), all the other regular appointments only consist of Doppler scan to monitor for baby’s heartbeats. Basically, we can’t see the baby at all, all we know from the visit is that the baby is alive. Anyone with similar experience as a sub patient in KKH?
