Has anyone else experienced baby measuring 2wks behind?

EDD 30/7/25

(Believed DD was to be 15/7)

First day of last period 8/10, strong positive pregnancy test 4/11 (first day of missed period would have been 5/11)

According to these dates though for EDD they said I would have conceived on the 4th Nov 😅 (didn't DTD that week, traced it back to 21/10)

Anyone else's little one's measured 2 weeks behind? They looked at me like I had two heads when I told them I tested positive (with a very clear line) on the 4th! 🤣
