Well if it it works for you then it's a success. And I'm not a woman, so again I have no basis to say what's needed. But my understanding is that a woman's "cycle" isn't literally fixed at once per month. So resetting your data into groupings by month obscures the natural periodicity which occurred.

Yeah, but the end of this month should be next to the beginning of next month. That is how time works. I don't wipe my mood slate clean because I turn the page on my calendar.

This doesn't make much sense to me. Are the dates of the month aligned next to each other? Why? Why is day 1 closest to center and day 30 at outer ring? Is there some relationship I don't know, like you get paid at the first of the month?
