SchnitzelvonKrummsverylowtum I only got measured at my 28 week appointment (when I was 27+6) next due to be measured at 30+6.
I don't really know how accurate bump measuring is, I've never measured big in previous pregnancies yet my last two babies were born on the 91st and 95th percentile, however I'm not sure if when I had them they were using a different method of calculating if your big.
Mw explained that Obv the measurements of a lady with a high bmi will be much greater than say mine when I'm naturally very petite. The graphs in your maternity notes should be tailored to you individually not just a standard same for every one.
Baby is certainly feeling big to me, his movements are so strong!
