A member asked:
What is my dates of conception if lmp is oct. 13 2014 and first ultrasound at 9 weeks gave me a due date of july 25 2014?
A doctor has provided 1 answer
Conception date: If your cycles are normal, your ovulation/conception date would have been Oct 25-29. The 9 week ultrasound could be off by 4-6 days, plus or minus. Your conception date, as given above, is completely compatible with the ultrasound measurements. The only people who know their EXACT conception date, are those undergoing IVF.
