@wyatts_mommy_0106 Is right it depends on the doctors office. With my first I got one at 20/weeks and didn't get another one. I am at a different doctor and I got the anatomy scan and then what they called a "sneak peak".

it depends on your Dr office and how many ur insurance covers I got my 2nd on at 19 weeks and I was supposed to get one at 36 weeks but didn't make it that far

Usually you don't get anymore unless there's a concern or problem
