Personalised fundal height charts

[GingerRodgers]

Just been looking at mine and have realised that to be on the 50th centile, I have to measure 2cm under gestational age?
I'd always read/heard that it should match measurements to weeks? Obviously + or - 2/3 to account for accuracy but my chart says if I match weeks to size then I'm measuring above 90th centile?
Any ideas? Any one else got a chart like this?

Bump

Yes, me. But mine's even smaller!

You have to measure more than 2cm under weeks measurement to be on 50th centile?
What is it with the charts?

Yes mine was like that.

I don't know where you are, in the Midlands/ Birmingham these have been used for years. They are meant to be more effective for picking up potential problems because they can see if the growth is at the correct rate.

I was always about the cm per week stuff I read on mn. From what I understand it depends on the height of the woman.

btw don't pay too much attention to the weight of baby stuff that is notoriously a load of bollocks ! I measured smaller with dd2 who was a pound bigger .
