Just a quickie about dating scans/due dates. At my 12 week scan i was told that i was two weeks further along that i was (i know exactly when baby was conceived - it could only have been one occasion!). Does this mean baby was just 2 weeks 'bigger' than he should have been? If so does this mean he'll come on the date they predicted or will it still most likely be 2 weeks after? Quite confused about this and no mention was made of my due date at my 20 week scan, so i'm guessing it's all progressing the same? xx
