First face to face meeting with OBGYN at 17 weeks

What to expect from the meeting with OBGYN at 17 weeks? I know OBGYNs cannot do ultrasound. And I have anatomy screening scheduled at 19 weeks. So what she is going to check? I just seriously want to cancel the meeting if that’s really non-required appointment like checking my weight/heights and Doppler which I can do at home myself.
