I had my 20 wk scan last week and everything was fine. Went for antenatal apt today and I have been told that due to my size(im quite overweight) I have to go for another scan at 28 weeks in order to assess the babys growth. Im sure this will be fine, but its started me worrying I feel quite weepy and anxious that its my fault my baby may not be growing properly ortoo much. I haven even checked what the risks are! Im aware about gestational diabetes, but still really worried. Anyone had this experience or any advice?
