Anatomy scan anomaly

Posting for my wife. Got our anatomy scan at 20 weeks. They found her femurs were 3% and a cyst like structure in her cervical region measured 14mm. Our blood genetic test was normal. We’re waiting for an appointment to get in with a specialist as our OB office has never seen one. So they couldn’t really tell us what it means if anything. They said don’t google anything while we wait for an appointment and a 6 hour round trip. Anyone been through anything like this?
