20w anatomy scan - doctor didn’t read results?

Went in for my anatomy scan today and met with doctor immediately afterwards. Doctor said preliminary results were fine, but they would get back to me after a more detailed review in a few days. I asked her a few questions about the scan (e.g., was cervical length normal (due to concerns about incompetent cervix)) and she was unable to answer. Is this normal? Should I be worried?

Addl context - they have ~10 rotating doctors in my practice and the one I saw today was *brand* new - like just graduated residency this year and started work this month.
