Hi this is a stupid question because I know that my baby is growing fine, I am 31 weeks pregnant and measuring 31cm so exactly right as far as midwife concerned. But I am plotting on the top line of the personalised growth chart thingy in my notes. Surely if I am average then I should be measuring in the middle? Also I am a large lady and had a high BMI before pregnancy does this mean that the measurement is likely to be out anyway because of my excess flab. I have a growth scan booked for 34 weeks but as you can probably tell I am petrified of having a large baby.
