Laney I was told at my 1st scan that bub was 5 days behind and because I was on clomid I KNEW that wasn't possible. I had a positive test at 11DPO! Don't stress yet. Bub just might be little and waiting for a growth spurt! At my next scan I was 1 day behind then at the next one I was 4 or 5 days ahead! I have my proper 12wk scan today (the others were emergency ones when I was bleeding) so we will see how big s'he is now! I know it's hard not to wirry, but this early it can truly mean nothing. xx
