No scan for subsidised patients

I am a subsidised patient at KKH. May I ask why do we need to see the doctor when they don't scan and jus ask how are you feeling? When you say all ok, nothing up, they jus give you the next appointment. Don't mean to be rude. If no scan and I'm feeling well, why do you need to see the doctor when they don't even scan baby every time you go?#advicepls
