I'm so ashamed - just been for a follow up anomally scan (the baby was lying in the wrong position at 20 weeks for them to check the heart properly) and the sonogropher really struggled to get a decent image because of my BMI - not sure exactly what it is but I'm 5'3 and a size 16. I was so embarassed I could have cried - anyone else had trouble with scans? Got to try to keep my weight under control!! :(
