19 week appointment

So I have my 19 week prenatal appointment today, i haven't had an appointment since I was 12 weeks. I'm just curious what they'll do at this appointment. He has canceled 3 times already so that even if he doesn't cancel on me again..... Will he most likely do the anatomy scan since it's been so long between appointments. I know what were having due to an ultrasound at 15 weeks at a place other than my doctors.
