20 week anatomy scan!

Georgia💚💙👶🏼🍼🐠🐟
So today I have my anatomy scan, we already know we're having a boy but he better stay a boy since we already have so much stuff for him 😂 but I'm incredibly nervous for some reason. All of the blood tests came back 100% perfect which is amazing but I'm just worried they might find something while doing the scan. I've heard mixed reviews about what happens if the tech finds something odd so tell me: 
A.) would a doctor come in and finish the scan and go over everything right then an there,
 B.) would they just finish the scan and have a doctor call me sometime later or in the next few days or so, or 
C.) would I find out at my next appointment? I'm so confused and worried 😩
