Easier calculation: Every pregnancy dating software is based on a 40 week pregnancy. Actually the pregnancy is not 40 weeks but 38 weeks. Not every women knows when they conceive but women know when their last menses occurs. Therefore the dating is from the last menses artificially adding 2 weeks to every pregnancy. ...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?

Sorry, it doesn't work that way because there is a margin of error in the u/s and there is no guarantee that you conceived exactly at day 14 which is what those calculators will assume. Best of luck. ...Read more
