Growth measurement-low measurement

Had my 32 week growth scan on Friday. Baby girl is overall 47th percentile which is good, but one of her head measurements (diameter) was just under 10th percentile (9.8). My dr didn’t seem concerned and thought it could have been her position since she’s head down...but she said I could go to a mfm dr for another ultrasound to validate measurements. Ultimately there’s nothing that can be done whatever the accurate measurement is, I just want to know.

Has anyone else had a lower percentile on this head measurement? Her circumference measurement was ok at 24th percentile, it’s just the diameter that was off.

Hoping it’s all just because she is petite like me ❤️
