If i am 9 weeks pregnant according to measurements. when is the possible date of conception?

More information: If you are 9weeks 0 days today, 9/30/13, then your possible conception date would be 8/12/13. If your ultrasound was on a different day than today, or if you were 9weeks 6days, then this date could be off. In addition, these conception dates are 'average' meaning that they are plus or minus a few days on either side. Hope that helps!

August 5 - 15.: If you are 9 weeks now, you most likely conceived between august 5 ; 15. Have you seen a dr? They should be able to give you a more narrow answer if they know your exact gestational age and due date.
