Reverse Due Date Calculator (("According to my calculations, given the baby is due on Friday, May 9th, 2014, this would put the conception date on or around Friday, August 16th, 2013"........ The 16th is the day we checked into our resort in Missouri! I guess if this baby is a boy, it WILL be Branson Donahue! LOL))
When you think about pregnancy calculators, you probably don’t often think about ones that count backward, but a backward pregnancy calculator is one that counts backward from your due date to the date where you conceived. While it may be hard to pinpoint the day you actually had sex, it can narrow down a window of time where conception was likely to happen.
