Are conception date calculators accurate if your 7 weeks and 8weeks ultra sounds due date are the same. I'm due April 26th 2015?
Yes, but...: An 8-week ultrasound scan gives an accurate estimate of the dates. All dates are estimates, so even an "accurate" estimate is an estimate. If general, there is no need to look for an exact date of conception, because life is never exact, and women are having sex with only one husband or future-father-of-the-baby at a time. So, the date estimate from the ultrasound scan is accurate enough. ...Read more

If my 8 and 12 week ultrasound gave me a due date of September 28th how accurate is the conception date and how far can it be off ?
Depends: The accuracy of the delivery date is variable depending on a number of factors. Usually the earlier scan is most accurate due to differences in gestational size (weight).

However, +/- 2 weeks is a good guess ...Read more

Dates don't line up: If your conception date is 2/11-12, as you say, then your edc (due date) will be about 11/18-19--which is close enough while only about 8 weeks pregnant to the 11/8-9 you mention. I don't understand the 11/4 reference. Early dating is less accurate than later ultrasound dates, so in about 10 weeks you will know much more. ...Read more

If due date was june 3 based on LMP of aug 27, then it changed to may 31 after u/s, could this be bcuz i ovulated sooner? Conception date different?
Yes to both. : Is very common to have the due date changed based on the findings at ultrasound. It is often around a month off because it is frequently such that one does not ovulate when they thought they did, but actually ovulated the previous month or in fact a later month. So your findings are common and should be believed because the early ultrasound is extremely accurate. ...Read more
