Anatomy scan redo

Hi all

Had my 20 week scan today. All looked great but I have an anterior placenta which he was facing and the little stinker wouldn’t cooperate for 2 of the required measurements so I need to go back and hopefully he will be better behaved. Thankfully they got almost all the major ones which were normal and the only ones missing are his lip and one view of his heart ( she said it looks normal but was jut missing one angle). Anyone else had to go in for a redo?
