This is what I do with my time when I have my period:

Yes, I know FF does stats. But I like getting my hands dirty… I like numbers… and most of all, I like to keep busy. I have a “Fertility Charting” binder I keep at home… it has all my charts in it, and now it also has this printout, our BD timing printout, and a list of notes from each doctor’s visit. I’ll keep any and all test results in there too.
