All dates are based around lmp- if you have had a scan the dates are based on baby's measurements. Early scans can give you off dates that don't always match up. I had 4 different due dates with my first- lmp was the 4th, first scan was at 8 weeks and given due date of the 15th, scan at 10 weeks moved me up to the 11th and scan at 12 weeks moved me up to the 7th- much closer to my original lmp date! (in a side note though- he was born on the 18th!&#128514

LMP and baby measurements. I was given quite a few EDD for DD2 from Dec 22 to all the way almost mid Jan! She came 12/22 though

They book the scan based on lmp because most women don't know their ovulation date (I have argued many times with Kaiser advice nurses about this) but what will measure on the scan will coincide with date of conception

Yeah baby measurements because according to lmp I was due 9th April then my private scan said 7th April (NHS 8th April) baby arrived on 7th x
