Baby bond dating scan
Had a pregnancy ultrasound that doesn't match your Estimated Due Date (EDD)?
MFM mums share their stories plus expert sonographers explain why it happens and what to do if you're told your due dates are wrong Listening to MFM mums, it's clear lots of you leave your scan with a nagging feeling that what you've been told that day doesn’t seem quite right.
Our 4D Bonding experience offers you the chance to meet your baby before it's born, and unlike your NHS appointment, your children, family and friends are welcome to share your experience.
Despite the fact that sonographers are experts in their field, estimated due dates (EDD) calculated from pregnancy scans can be incorrect, as Ollysmum76 discovered.
The best time to establish this date is at the scan you are offered between 11 weeks and 2 days and 14 weeks plus 1 day,” Experts say that the scan date can sometimes come out as less pregnant than suggested by your LMP. “My 1st scan with this baby put me 1 week earlier than I thought I was.
But then again with my first baby I was spot on with dates, he always measured big and he was a week overdue... Babies are ready when they're ready - try not to worry (easier said than done).” But Nigel also says that the estimated (and that is all it is) date is normally accurate plus or minus about a week.
There would be so many variables if it was calculated from when you think you conceived, especially as everyone's cycles are different and the fact that you don't necessarily conceive on the day you have sex!
Pregnancy normally lasts from 37 weeks to 42 weeks from the first day of your last period, explains NHS Choices. This is especially true if you have an irregular cycle or have been on the Pill for example.
