EDC stands for Estimated Date of CONFINEMENT, not conception. Of course it could be wrong. It is just an estimate. If it is from a doctor, be sure to take it into consideration, though. It may not be perfect, but a medical expert's advice is always best to follow. An ultrasound will give you a more accurate date if you are unsure of your last period.
doctors are rarely 100% accurate on the date that a baby is actually conceived. however, the methods they use to calculate a conception date is never off by more than 2 weeks either way. the earlier a blood test or sonogram is done, the more accurate it will be, usually within a few days.
The approximate date of conception was September 1st
That makes your estimated conception date April 18th 2011. However, this date could be wrong by a couple of days. It all depends on when you actually ovulated.
I will assume you are talking about December 3rd 2011. If so, that makes your estimated conception date March 11th 2011. The estimated conception date is not always completely accurate. It is often wrong by a couple of days.
That makes your estimated conception date February 13th 2011. However, this date could be wrong by a couple of days. It depends on when you ovulated.
No, you count back 38 weeks for the conception date, but don't forget this is just an estimate.
That makes your estimated conception date March 8th 2010. This date could be wrong by a couple of days though. It also depends on the date on which you ovulated.
That makes your estimated conception date March 10th 2011. However, this date could be wrong by a couple of days. It depends on when you ovulated.
That makes your estimated conception date April 22nd 2008. This date could be wrong by a couple of days though. It depends on when you ovulated.
That makes your estimated conception date February 13th 2010. This could be wrong by a couple of days. It depends when you actually ovulated.
A reasonable estimate would be around 31st January 2007
That makes your estimated conception date March 14th 2011. However, it could be wrong by a couple of days. It also depends on when you actually ovulated.
Your estimated date of conception would be November 13, 2008. Aug 6th, 2009 is my due date as well.
