Call back after 20 week anatomy scan

Micah

Got a follow up call after my 20 week ultrasound saying baby has a small choroid plexus cyst, and they want me to come back in for a few more pictures. They didn’t say this, but after googling, I’m sure they want to rule out Trisomy 18. Has anyone else been through this? I know the chances of it being that are slim, but still terrifying nonetheless!
