Echogenic focus

Hey y’all so on the 20th I went in for my anatomy scan at 20weeks 3days and they found an echogenic focus on my son’s heart. Everything else measured normally, his brain, limbs, body, organs, etc. but since I didn’t get any genetic testing done in the first trimester my OB recommended I get some. She told me that it can be a marker for Down’s syndrome but since everything else looks normal, she thinks it’s nothing to worry about. I got the genetic testing done and am waiting for the results but I was wondering if any other mama went through this?? It’s tearing my nerves so bad waiting for these results. What were y’all’s results??
