The gestational age is counting from the first day of your last menstrual period. Therefore if you have a normal 28 day cycle than conception would have occured sometime during the week 5 weeks and 4 days ago. Conception occurs at ovulation which occurs (in a woman with a 28 day cycle) at around cd14 through cd20. Using this method you can pinpoint (within days) when conception was most likely to occur.

What is the conception date if the ultrasound today says the fetus is 12 weeks and 6 days old?
To determine the conception date based on a fetus being 12 weeks and 6 days old, you would subtract that gestational age from today's date. Since gestational age is typically calculated from the first day of the last menstrual period (LMP), you would subtract approximately 13 weeks (or 3 months and 6 days) from today's date to estimate the conception date. This would mean the conception likely occurred around 3 months and 6 days before today.
Can you work out a conception date from scan dates?
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.
What is a fetus's gestation age and due date when the LMP is unknown and can you count back the weeks at a dating scan to see when possible conception occured?
When you have a dating scan the scanner compares the size of the fetus with the size of fetuses of known gestation. The gestational age assumes that the mother has a regular 28 day cycle and got pregnant 14 days before a period. the gestational age is calculated from this notional LMP. This is accurate in about 85% of cases. If you don't know your LMP and have been given an EDD/gestational age you need to take off 2 weeks to find an estimated date of conception. this website will help you. http://www.genetree.com/about/conception-calculator.asp
November 21st 2008 you were 27 weeks and 3 days pregnant when is your conception date?
When is your due date?
How many weeks pregnant are you at 81 gestational days?
11 weeks and 4 days
If an ultrasound showed you were 19 weeks 2 days pregnant can you count back to see when you conceived?
Ultrasound gives an estimate of the age of the foetus. At this stage of the pregnancy, it's quite accurate, but it's still only an estimate, and the date of conception could be a few days, even a week, away from the date 19 weeks and 2 days ago.
You had a period on 08.06.06 and the early scan date said you were 10weeks and 5 days on the 25th August is this a conception date or lmp?
LMP. Conception date would have been about 2 weeks later.
If due date is March 22 2010 when was conception?
June 18th 2009. Due dates are counted from time of pregnancy.
When is the conception date if the baby is born January 2nd?
Based on a normal gestation period of 40 weeks the conception date was April 11th 2009.
When was my baby conceived if on July 21st I was 11 weeks and 1 day according to my ultrasound?
Conception date is based on your last ovulation cycle prior to when you didn't get your period. But this can be incorrect if you didn't conceive when you was ovulating. Alternatively you can have a ultrasound scan which will give you a conception date but this can be off by 5 days.
Your girlfriend is pregnant and on the ultrasound said GA edd 19 weeks and 0 days but that would place conception to almost 3 weeks before you had sex what does this mean?
They count the weeks of pregnancy back to the last date of the first day of your menstrual period, not to date of conception. For example, I am considered to be at 15 weeks. The first day of my last period was 11/25/08 and the date of conception was anywhere between 12/9 and 12/16
What is the conception date if the ultrasound today says the fetus is 8 weeks and 4 days old?
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
