12 week check

Zuleika

So I didn’t get a 12 week check on baby I had a 6 week and I have been told I won’t do another check until 20 weeks is that normal or do you usually get a 12 week check? Just asking cause this is my first and I have regular scheduled ob appointments but mainly they just bring the Doppler and see if they can find baby’s heart rate, which they found 2 times but I’m just confused because I see so many people saying they have 12 week checks.
