How accurate is a scan date?

A scan date is normally spot on although if theres a few days difference between the scan date and your date they will go with your dates. I think mine was spot on, 12 weeks 2 days was actually 11w6d which I agreed with but they are not infallible. Doesnt really make any difference as my daughter was 3 weeks early.

Are dating scans more accurate than LMP?

(I already have twins) ps Congratulations! i meant to add: dating scans are more accurate than LMP, as you can ovulate any time in cycle... (although certain days are more likely) and sperm can hang about 7 days... Being pregnant can give a positive result on an ovulation test because the hormones are similar chemically (as I understand it).

Is it common to miss a scan date?

Its really common not to do this. A scan date is normally spot on although if theres a few days difference between the scan date and your date they will go with your dates. I think mine was spot on, 12 weeks 2 days was actually 11w6d which I agreed with but they are not infallible.

How accurate are early scans at 12 weeks?

Early scans can be out by 5 days or so but I thought by 12 weeks they were regarded as fairly accurate. 3 weeks is a big difference! I dont think they would be that far out. Perhaps you ovulated twice that month? I was sent to EPU as was being very sick. By my dates I was 7 weeks, by theirs I was 6 weeks.

What happens if my scan date is different?

If the scan date differs from your last period dates, the scan date will be used. The scan will usually show that your pregnancy is less far along than suggested by your LMP. This means that accurate dating reduces your chance of having your labour induced because your baby is thought to be overdue.

When is the best time to have a scan?

These can be carried out from week 5 or 6 of pregnancy, which is a notoriously tricky time to be accurate on dates. Understandably, when it is such early days it’s easy to worry when the scan dates are different to what you were expecting.
