There's an app. for that.

You can always count on the iPhone to have literally every application imaginable.

Apple has an application that maps out your menstrual cycle, and lets you know what days are the best to be makin' love in order to get that baby in the oven.

They also have one that, based on when your last menstrual cycle was, can tell you when the baby was conceived, when you will be entering each term, the due date, the number of days left and the astrological sign of your child.

So ridiculous.

Check it out.
