Was your estimated date of delivery based on your scan at 4 months?

i went to have a scan on the 14th december, they told me i was 22 weeks and 4 days! hope this helps?
Expert:  Dr J Burk replied 7 years ago.

Not really.

Scans give the most accurate measure of gestation the earlier they are done - so a scan at 7 weeks will be a lot more accurate than the one you had.

Based on your scan - conception would have been on July 25th.

However that could have been the result of intercourse up to 5 days previously.

If you are uncertain as to the paternity of your child then you will need DNA testing to give you a conclusive answer - unless you only had the one sexual partner in July.

Hope this helps.

ok thanks! im quite confident if you are saying july time isit possible to be any earlier or later! thanks

Yes it is possible - it really depends upon how well your baby was growing when you had the scan which is variable.

As an estimate I'd certainly allow two weeks either way.
