Redo anatomy scan

Randi

Hi, so I was wondering if anyone had a similar situation. So I had my anatomy scan at 20 weeks but they couldn’t get all the things they needed. So I came back today (27 weeks) and they got some but still couldn’t get some because of how he was laying down. They have me coming back in a week (I’m moving or they would have had me come back in two weeks). Is this normal? If they were concerned or saw something concerning would they have me come back sooner? Just hard not to worry.
