Growth Charts - Any Connection?

[Chichz]

Hi ladies,

I know I'm overthinking this and should probably message the midwife if I'm worried, but wondered if anyone has any pearls of wisdom as I can't find an answer to this online:-

I had my 25 week appointment yesterday. I think my bump is pretty small, but I am fairly petite. Midwife was happy with it and everything else and said my fundal height measurement was good. When I looked at the chart after I'd left, it looks like it's plotted around the 15th-25th centile, which again would make sense based on my size!

Then I made the mistake of looking back to my 20-week scan charts, where they plot various lengths from the ultrasound - femur, tummy and head I think? The way these are plotted puts baby more at the 45th-50th centile on those charts!

As I said, midwife was happy but then I don't think she looked at my scan notes (different clinic). So, would we not expect a similar 'centile' for all growth measurements, even on different charts? Has anyone had anything similar?

Thanks from a confused FTM! x

Giving myself a bump - this chat moves so quickly!

At my 20 week scan baby was measuring around 90th centile for most things and the head and abdominal ones were off the chart!! (which worried me!!) - since then I've had a 32 and a 36 week growth scans and measurements now just over the 50th centile for everything - I think baby just takes time to even itself out - but if you are worried don't hesitate to contact the midwife and just ask her to double check for you, maybe use the excuse as it's a different clinic you just wanted to check the way they plot the charts are the same, or something like that :)

Ultrasound measurements will almost always be different centiles to fundal height measurements - you’re comparing apples with oranges. If you’re petite and have less-than-average fat covering on your tummy then your fundal height measurement will be less than average also, even if your baby is exactly average sized. Wouldn’t worry at all - but if you’re concerned, ask your midwife.

Sorry ladies, posted a reply before and for some reason it hasn't appeared.

@NicNac100 That sounds reassuring! I will definitely contact her though, just in case she's missed those notes. Perfect 'excuse' as you say!

@TenThousandSpoons0 Makes sense 're. tummy fat. I was pretty slim for me when I fell pregnant and haven't gained many kgs yet.

Thanks for your replies
