Is it normal to not have an ultrasound in the third trimester?

I’m 30+4 now and haven’t had an ultrasound since the anatomy scan at 20 weeks. My doctor at the time said they wouldn’t be doing any ultrasounds until the birth unless they suspected something to be wrong. I had to switch doctors because I moved four hours away and they said the same thing about ultrasounds when I asked out of curiosity. Is that normal?? I feel like I see so many people having ultrasounds around this time in their pregnancy lol. I don’t mind it but I just really miss getting see my baby and don’t want to pay a lot for a 3D one at some place
