Apparently there's a science to spitting just right. I threw more money at the problem and bought my Ovulation Scope last night. I'm not a patient woman so I opened it in the car and drooled on it right away. However, you're supposed to wait for it to dry for 10 minutes. You're also not supposed to have have eaten or drunk anything for 2 hours before using it. So I spit again this morning, but apparently too much, because the stupid thing wasn't dry in 10 minutes. I bought it because I thought it'd be easier than taking temps every morning (the packaging trumpets, "no complicated charting"). Uh-huh.
