I went for my 20 week scan today, (I am 21+1), all was well but I am panicking slightly about one of the results. The baby was measuring average or just a little bit over for everything apart from abdominal circumference which was 169.2mm and on the 85th centile. DP has been joking about the baby being chunky and I feel terrible! Have been trying hard not to eat too much rubbish but have succumbed to a Magnum or Minstrels on a few occasions as of late. Could my diet have led to the baby measuring bigger than average in this one area? Advice would be very much appreciated.
