I think so. I think if you use the first scan gestational age and minus two weeks that gives the approximate conception date giving a few days either side.

Count back 2 weeks, so 6 weeks and 4 days old. Count back 6 weeks and 4 days old on a calendar and that would be an estimate. Also, check out www.babymed.com, and put in you're due date or you're last LMP and they can tell you an estimate of conception. God Bless


Why do they go by the the first day of your last period instead of conception?

Because women were falling pregnant before midwives knew about the science of conception and implantation, the only date anyone knew for sure was the date of the LMP (last menstrual period). Also, just because you have sex on a day, does not mean that you conceive on that day- sperm take several days to travel to the ovum, and so the actual date of conception will remain a mystery. When you have your first ultrasound scan, you will be dated based on the size of several parts of the foetus' body, include head circumference and femur length. This will give a much more accurate indication of gestational age, and if you work backwards, you can calculate the date of conception- remember though that the act of love making would have happened a couple of days before. Hope this helps! Aj :)

Normally 9 months from conception. To work out the expected date of birth, take the first date of your last period, add 10, minus 3 and add one year. Example: 01/04/2009 = 11/01/2010.
