Measurements on scan photo....

[WeLoveHaribo]

Do these mean anything ( Im sure they do but any significance to size of baby?)

My 1st DS

12wk- 7.7cm
20wk- 15.2cm

This pregnancy

12wk- 12cm
20wk- 13.6cm

Anybody know? Is this size of baby? Thanks in advance. Xx

It depends what they were measuring at the time. The most obvious would be the crown-to-rump measurement (top of baby's head to bottom) but at 20 weeks they measure a lot more things I think, so it might refer to something else? Best ask midwife to interpret for you.

I figured it was crown rump, and yeah much more measurements taken at 20wk. But these measurements are at top of scan photo. Was just wondering really want are.
