Question: Conception Date


 amandab101 - Fri May 08, 2009 5:38 pm

I'm having a little trouble figuring out my conception date. My LMP was November 23rd, giving me a conception date of around December 8th. But, my doctor gave me a EDD of September 11th which gives me a conception date of December 19th. Both ultrasounds I've had point to this date...which one is more accurate?

User avatar Hello,
Ultrasound dating is the most reliable so I would go with that one when there is a discrepancy. Further ultrasounds typically done at the mid-pregnancy point may further verify this. When it comes right down to it, the baby will come on it's own schedule and rarely is this on the estimated due date.

Best wishes.
