fetal echo for ivf?

IVFmom
I had my 12 week NT scan today and everything looked good. My OB said that we'll have to do a fetal echo since this is an <a href="https://glowing.com/glow-fertility-program">IVF</a> baby and they do them for all <a href="https://glowing.com/glow-fertility-program">IVF</a> babies. Anyone had this done or heard of it?
