anatomy ultrasound?

Amber • Mommy to a perfect 2 year old little girl! And just found out I’m pregnant with my second baby! ❤️
I just had an ultrasound yesterday at 18 weeks and then going for my anatomy one the 24th so will be 20 weeks, he told me everything looks great, is there something that could show up on the anatomy one that he didn't see? I'm so worried about everything and i know I shouldn't be, just feels natural lol.
