I don't know if this has happened to anyone else but I went in for a scan today thinking I was 11 weeks and 5 days only to be told that the baby is measuring at 9 weeks and 5 days.
Heart rate was fine and they said not to worry because everything looked good but I am still worried.

I thought my dates were right, maybe they weren't but this has really freaked me out.

Should I be worried?
