Ok guys crazy spiral here. A couple of weeks ago we had a scan and baby’s measurements were all on point other than the abdomen circumference which was 5 days ahead. I just saw a video online of a woman who had that at a scan much further along and apparently this can be a sign of gestational diabetes


now I’m panicking about my diet and having a huge overweight baby.. arghhh! I’m 20 weeks tomorrow. Husband is 6ft4 and I’m 5ft11, I’m on the overweight BMI thing but I think it’s
bull (I lost 4 stone last year and was at my lowest weight ever and still considered overweight even though I was comfortably in a 12-14) so I’ve not been caring too much til now.. sorry this may seem really ridiculous but has anyone got any reassuring stories about measuring ahead?
On my growth scans and fundal height I’ve been measuring weeks ahead. Like one week for tummy, 3 weeks for head or however it was and it’s switched and changed, legs have always been average though. GD test was fine.
Last baby was 7lb at 39+1, this baby is projecting well over 9lb (I got as big and heavy as I was at term last time by 33 wks) and I’ve done nothing different but be a bit older.
Both OH and I are shorter side of average, I’m Normal BMI (always been quite small until about 4 years ago) he’s pushing into overweight.
You don’t just eat your way to GD or a big baby unless you’re going absolutely silly. There are some studies that link baby’s size to your diet as a child even.
So long as you’re not doing anything reckless, it seems to be pure chance.
ETA: actually, I don’t think there’s really any such thing as measuring X many weeks ahead in real terms once you get past the CRL in the early stages and into centiles. There’s the average size of babies at said week. So when I say I’m 3 weeks ahead it’s just saying most babies at the size would be 3 weeks older, but there are still plenty of babies under and over those sizes. If that makes any sense at all.
I.e Although baby was 6lbs at 33+4 with an off the charts AC, they were 90th centile overall. Which means in 100 babies at the same stage, 10 would be bigger and 89 smaller.
If they’d measured that weight at 36+4 they’re be right in the middle.
