Pregnancy (Definition)

When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Are conception date calculators accurate if your 7 weeks and 8weeks ultra sounds due date are the same. I'm due April 26th 2015?

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 ?

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, the US is a predictor of age of the fetus not the delivery. The fetus could come early or late even if it is at the due date because labor is not exactly coupled to the fetal age. However, +/- 2 weeks is a good guess ...Read more

If your due date is november 4th and your conception date is february 11-12 how is that possible if you had sex november 8th or 9th?

If your due date is november 4th and your conception date is february 11-12 how is that possible if you had sex november 8th or 9th?

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

1/7/2014: Is the best estimation of the date of conception. The 8 week ultrasound establishes your due date +/- 5 days. Therefore it could be few days before or after. Period dating is the most accurate if you are sure of your last period. ...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?

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
