Can u tell me the possible conception date if my due date is 26th september 2013 pls?

EDD: A edd of sept. 26 would likely mean conception close to january 2. If your last period was on or close to december 20 that makes it extremely likely. These are calculated guesses based on 28-day cycles and 40 week pregnancy, so they may not be correct for you.

Not with certainty.: An estimated delivery date of 26 sep would likely be based on a last menstrual period (lmp) of 20 dec. If that is the case, an estimated date of conception is probably around the 3rd of january, give or take a few days.
