Normal appointment separations?

I have an appointment in a few days, I’ll be 19 weeks 6 days. It’s just a normal appointment, they take me in and check the heartbeat and everything and I’m done. And then they only schedule me every 4 weeks at this point, so my next one won’t be till I’m 23 weeks. And I haven’t had my anatomy scan yet, I’m honestly a little mad I’ll have to wait till 23 weeks, my first born I got it done right at 20 weeks. Do you think maybe they’ll notice how far along I am at this upcoming appointment and be like “oh well let’s go do the scan right now.” Or they’re really gonna make me wait even longer?
