Would someone be so kind as to remind me how the whole "calendar method" works? I know its unreliable to depend on as far as not getting preg goes, I know sperm can live inside of you for days and what not. If memory serves me, then up to 15 days from the begening of my last period is the time I would (in theory) not be able to concieve...or maybe I have that totally backwards... hell I don't remember. I have virtually zero females in my life, so its hard to retain this kind of information wthout ever talking about it. Anywho, any help is much apreciated.
