Pregnancy Timeline Estimate: Calculate Your Conception Date


Question
I had a period between 22-26 Oct 07, Can't remember the exact date. My due date was 28 July, after the ultrasound they change my due date to 18 July 08. Can you give me a estimate date of when i got pregnant. My period last 3 days. Thanks

Answer
If you ultrasound was performed early on, prior to 10 weeks, then you most likely conceived sometime the week of October 26.  If that ultrasound was performed after 10 weeks, then it can't be relied upon for accurate dating, and because there is such a wide range of normal for cycle lengths and ovulation times, I can't give you a better estimate.
