Ultrasound schedules

With my first, I had routine ultrasounds scheduled to confirm pregnancy @ 7 weeks, then another one @ 12 weeks and then the anatomy scan @ 20 weeks.

I’m just curious if this is routine for most practices? My doctor’s office hasn’t mentioned another u/s for me @ 12 weeks. I’m going to ask them when I go on Friday but was just curious what everyone’s experiences were.
