If you had an early scan, how much did your due date change at your dating scan?

Hi ladies, I had an early scan at 8 weeks that put me back 6 days from the dates of my LMP. The sonographer told me that it'll likely change as it might be due a growth spurt, so I'm just wondering how much (if) your dates changed between scans?

I'll be 11+3 at my scan, but hoping to be put ahead past the 12 week mark

LMP 16th, 7 week scan 12th, 12 week scan 14th.

I remember my scan at 6 weeks gave me a due date of the 8th,an 8 week scan changed it to the 3rd, a 10 week scan changed it to the 27th of the month before and my 12 weeks scan changed it back to the 3rd! She was actually born on the 10th! So make of that what you will

6 week scan dated me 24 December. My calculation according to cycle (we only dtd once) so I know accurately around when I ovulated, was 23 December. My 12 week scan 20 December.

Went for early scan knowing I was 8 weeks exactly from LMP. They dated me as 6 weeks 6 days so 8 days behind! I knew my dates were exact and have 28 day cycles.
I went back to same place at what I knew to be 11 weeks and they dated me the same 11 weeks exactly so within 3 weeks baby had caught up to correct dates. At my 12 week scan they gave my EDD as the one I had all along myself worked out.

I was 2 days behind at 6 weeks, exactly correct at 8 weeks and then 2 days ahead at 10 weeks which was what was used for my due date. I'm pretty sure of when I ovulated so I think her due date is later than they said (but only by a couple of days so guess it doesn't really matter).

I had the same Dr doing the scan each time which is maybe why it was fairly consistent.
