Cystic Hygroma

I had an ultrasound a couple days ago. And I got results back that I had a "cystic nuchal mass highly suggestive of cystic hygroma. Measures approximately 4.3 mm in AP thickness. This is often

associated with aneuploidy. Recommend further evaluation via high risk

obstetric provider and genetic testing"

The ultrasound took close to 30 minutes but I didn't think much of it because they said they were having trouble identifying my right ovary.?

Is anyone familiar, I've done a bit of research and I've called my ob but I haven't received a call back yet and it's been 2 days. Been worried😞
