Get the pregnancy tracker on here, I already knew my conception date and it got it right on here, so maybe that will help some.
August 3rd if your due on the 26th,
Thats odd that your first 2 scans were measuring the same...I guess baby was a late bloomer at first.
My due date is the same, and my lmp was July 20th. Conception on or near the 3rd of August. Nothing is really accurate in knowing the exact day of conception.
Anyhow, hope this helps.
the scan at 12 weeks 5 days was 18th october
