You know you've been charting too long when you pack an OPK in your lunch box so you can test your wee in the afternoon while you're at work!!!
Oh wow - that's being prepared. What happens when your DH takes your lunchbox by mistake?

Audax - thanks for the offer. I'm taking it as a sign to not get too obsessed about things. If I decide to get obsessive again, I'll let you know. I mean, even more obsessive. I may buy a microscope instead and peer at things through that to fulfill my inner nerd.
