I am also from NUH. Was told the 32 weeks scan was the last. I asked gynae about it and she told me they will scan again if baby never comes out by due date. For now, they will just check the baby's heartbeat, measure the fundal height of your tummy and ask you about your overall well being.
I did have ultrasound scan done at kkh. To check the baby weight and amniotic fluid in the placenta as baby has no sign of coming out yet.
I had my last scan at 36 weeks and nothing can be seen cos baby too big by then haha.
Check with your gynaecologist again. Usually last one is between 34 - 36 weeks
