Anatomy ultrasound question

Khyrstin β€’ I am happily πŸ‘« with πŸ‘§πŸΌ3, πŸ‘ΆπŸΌ19mo, πŸ‘ΌπŸΌ July 2017, and 🀰🏻due 3/9/20.
I had my anatomy ultrasound today and it went great! Everything looked perfect. BUT baby was in a bad position and they couldn't see the spine. SO my doctor gave me the option to come back and see if she moves or to go get a level 2 ultrasound (as that's what they'll do anyways if they can't see it again). So I opted to do it! Has anyone had one? What's the difference? What should I expect?!?!
I'm just glad everything we did see looked perfect!!!!!!! πŸ˜πŸ‘πŸ»πŸ‘ΆπŸΌ
