Anatomy scan scheduled for 17 weeks...?

A

Anyone else had/having an anatomy scan this early? My last baby I went in a 20.4 (same MFM office) is there a reason to do it early? Any reason to ask them to put it off for a few weeks?

I’m not personally worried about this baby, I’ve seen him twice and he’s been active and ahead of schedule each time but I’m not sure of going early means they may miss something? 😬
