HI hun, just to make u feel better im also small and at my 30 scan they said that she is measuring at 4lbs and 10oz already and that she is in the 97th cent of her growth,i just have to have extra scans done and now have to have my 3rd gtt test done nexxt week again.but its only a guide line so try not to worry usually they are not right anyway.
