LMP measuring week early in dating scan??

[goldie555]

Is there any reason a lmp would measure a few days early in an early dating scan?? Does that mean I was pregnant BEFORE that lmp?

Dating scans can be off up to a week. Also, you could have ovulated sooner or later than you thought. It's nothing to stress over.

At 7 weeks 3 days it was about 2-3 days further ahead than my lmp, at 11 weeks 6 days it measured 6 days further ahead than lmp. Does that mean I ovulated earlier in my cycle than normal??

U/s are always give or take a few days...i was 20w exactly my last scan and measured 20w3d...the one befor that i measured 3 days behind...i wouldnt put too much thought into it unless its a large difference...but a week isnt that far off...
