Anyone have experience with a Dr or tech saying that the baby’s head circumference is measuring a little small? I heard two stats 3% and 10%. Didn’t catch what was what.

I’m almost 24 weeks with my Rainbow Baby and everything has been fine until today... nuchal scan was fine, genetic testing fine, heartbeat fine, blood tests fine, fundal height fine, everything else in the anatomy scan was fine...

Just a little concerned. Going to a high risk ultrasound place in 3 weeks for another scan to check.
