Hey, I think that's the growth scan appointment at KKH or whichever hospital you're booked at. They'll do an ultrasound to check your baby's size, make sure everything is measuring on track, and check the amniotic fluid levels and placenta position. The whole thing takes about 20-30 minutes and it's quite straightforward, so don't worry too much about it lah. Just bring your IC and maternity notes, and if you have any concerns about baby's movements or anything else, that's a good time to ask your doctor as well.
