Reverse Calculate Your Due Date

New to me, but perhaps not new to you, is the website Babycenter.com. Your register over there, for free, and they send you the occasional update, with all sorts of clever info. One such bit of info, I am now going to share with you.

When you figure your due date, one common method is to take the first day of your last period, count forward 40 weeks, and there you have it, your estimated due date.

As the babycenter email indicated, there is a tricky math alternative. Here's what you do:
-take the first day of your last period
-subtract three months
-then add seven days

It sounds counterintuitive, I know, but Proud Mommy and I both ran the numbers, and sure enough, we both got October 27.
