Yeah, it's not always accurate. I'm also measuring 3 weeks ahead so they're doing a growth scan just to confirm my baby's weight. He's such a big boy!
Im from the uk they did the measure with the tape while lying down & my midwife didnt seemed concerned
My first baby was like that. She came out 8 lbs and 10 oz.
At 32w5d my baby weighed 4lbs7oz the ultrasound tech told me that that's the average weight for how far along I was. Hopefully they're a bit off on your baby's weight! I think that's kind of big for 31w6d.
At my 32 week scan my baby was 6.1lbs doctor says that is perfect
I agree it's not accurate ..
In the UK they don't tell you how much they are going to weigh they just do the measurements and tell you of baby is small average or big lol
Their not always accurate.
