If my due date is 26th may 2010 and last period was 10 August 2009 when did i conceive?

To calculate the estimated date of conception, subtract two weeks from your due date. Since your due date is May 26, 2010, subtract two weeks to get May 12, 2010. This is the approximate date of conception.

It's important to note that conception can occur within a range of days during the fertile window, which typically occurs 12 to 24 hours after ovulation. Therefore, the actual date of conception may vary slightly from the estimated date.
