May 21 of the prior year would be the approximate date, plus or minus a couple of days or so, as the issue is rarely so well determinable from such an uncertain time as a projected due date, because it is not clear how your due date was determined, and how accurate it is.

See http://www.vaughns-1-pagers.com/biology/gestation-periods.htm.

Nine months less 8 days from conception to delivery is typical (266 days). Thus counting backward nine months from February 13 gives May 13 of the prior year, less 8 days makes the date of conception about May 21 of the prior year, but it could be a couple of days either side of that in actuality.

One can also calculate 280 days, or 40 weeks, from the first day of the woman's last menstrual period. See http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Baby_due_date?OpenDocument

but this does not give you the date of conception, it only relates the due date to the first day of your last menstual period. As this website noted, only 4% of births actually occur on the date predicted.

If your last menstrual period was May 13, your ovulation should have been approximately between May 26 and May 28, which is when you likely would have conceived.

It depends on whether May 13th was your due date or not. If it was your due date, this makes your estimated date of conception August 19th 2009. However, this date is give or take a few days. It should not be used to determine paternity either.

That would make your estimated conception date January 19th 2011. However, this is give or take a few days. Often it depends on when you ovulated as well.

You likely ovulated somewhere around February 10, 2010.

Roughly May 22nd 2009, give or take a few days. However, it is difficult to accurately say when a conception date is. Therefore, I suggest talking to your doctor, midwife or obstetrician about it.

additional to the question it just doesn't make sense to me,my last period was february 14th i usually have a 30-35 day cycle but according to all these websites i ovulated way before i would have sex and to my knowledge an egg only lives for upto 24 hrs after its realeased so how am i pregnant? according to my due date my last period should have been the 26th of february which that's a negative i had it on feb 14th. so i guess my question is did i get pregnant on the 11th a couple days before my next period or on the 6th?

Your conception date is approximately 9 months prior to your due date or January 13. Remember, a due date is an estimate and, consequently, a conception date is an estimate as well.

A calendar date is a proper noun. For example: My brother's birthday is on February 13. "February 13" is the name of specific day;hence, it is a proper noun.

The estimated date of birth is June 6th

Your estimated date of conception would be November 13, 2008. Aug 6th, 2009 is my due date as well.

Take the first day of your last period and fourteen days, This is the time when a person is most likely to concieve. If I did the math right, looks like you became pregnant around April 13
