I have had my scan. Got it last Thursday.
Did u already do ur fetal anatomy scan? If so, they r just giving u estimated dates based on measurements. It's usually always going to differ, but if uve had a dating scan earlier in ur pregnancy then that's usually spot on. My baby measured 1 weeks ahead of his gestational age and 2 weeks ahead around his abdomen, the due date never changed tho. Babies grow at different rates I believe after the first trimester.
