Since my due date is jan 15th 2014, would i have conceived sometime in april? or in march?

April 24th : This is your likely conception date based on your due date. You can use a free reverse due date calculator on the internet to check this yourself.

4/14/13: With a due date of 1/15/14, then your 'average' conception date would have been on or around 4/14/13. Of course, these are 'approximates' and it's possible you conceived a few days earlier or a few days later, but typically not off by more than 5 days if you were dated with a 1st trimester ultrasound. Hope that helps!
