Has anyone else had this yet? I went in today for a happy 18 week ultrasound and then I was told that my son has two choroid plexus cysts found in his brain. I now have an appointment scheduled with a Maternal Fetal Specialist for next Wednesday. I had the harmony test done when I was 10 weeks pregnant and it came back that everything was normal, no chromosomal defects. I really don't even understand what it is, but I'm super stressed and sad bc it is something that didn't come back perfect.
