I wonder how someone would just find this..hahaha. But why would you say it's fairly accurate?

Hmmm....When was the first day of my menstrual period.

Because it's accurate for me, up to the appx. due date.

Oo. I don't remember my exact dates though...

Damn, I'm pretty fertile right now.

Hell, I'm fertile all the time.
