Anyone else's baby had a slightly small head at 20 week scan?

[Yorkshiremum]

I had my scan today at 19 weeks 6 days and wonder if anyone else has had a baby with a slightly smaller head measurement (it was 19 weeks 1 day)?

The midwife said that within a week is ok but the fact that she mentioned it at all has made me worry a bit.

The FL (femur length?) was 19 weeks 4 days so somewhere in the middle!

They always do this to me at all of my regular growth scans but i've always been given the reason that babies sometimes have growth spurts in different areas at different times - in one scan my baby had really long legs, enough for two midwives to mention it seperately, and in the next scan his tummy was a week too small for his gestation. In the latest scan...everything as it should be! I wouldn't worry too much - always easier said than done though!
