Anatomy ultrasound question

Ultrasound question ladies

I ask my OB when I would have my anatomy scan and he said not till 20 weeks but then he scheduled an ultrasound for my next appointment. I am high risk so I randomly get ultrasounds but I'm scheduled for an ultrasound at 19w6d will they do my anatomy scan then it will I more than likely have a different ultrasound for the that? I totally forgot to ask before I left the office and just curious
