Head circumference low percentile

[Blueberry1990]

Hi did anyone else have quite a low percentile for the head circumference?

I had my 24 week scan and the obgyn said everything was perfect all measurements etc but I've done the percentile calculator when I got home and got the following:

Biparietal Diameter 45%
Head circumference 6.7%
Abdominal circumference 47%
Femur length 45%

Someone's head has to be at the smaller end. That's how it works

I and both my DC have small diameters ( occipital not very prominent). Both of them had ultrasound before their soft spot closed just to check everything ok. We all find it difficult to buy an adult hat; that is literally the only issue now that they are adults.
