Also, during my scan the sonographer said my baby looks 17 weeks. But he is supposed to be just 16 weeks today. Is this normal? I told her that, then she said, well he lookes about 16 and half weeks. During my 12 week scan, I was sure the baby was 12 weeks 2 days and it turned out he was 12 weeks 4 days. But now, after the corrected dates he still looks a little bigger then what he should be at 16 weeks. I know its only a few days bigger, but still I wonder? The sonographer didnt seemed fussed about it.
