I might try to re-create it in Adobe® Illustrator and see if I can't sell it! I think I'd make it to be used for 4 cycles, just like mine is. I would probably have to include pens in 4 different colors though, since the 4 cycles will be on top of each other. This also makes them easier to compare, in my opinion. You'll really be able to see how regular your cycle is, if at all.
Just a thought. I don't think it would be that difficult. Might give me something to do.
My cramps have completely gone away...yay!
Cried over my Zumba® class b/c no one showed up.
Tired/Dragging--but I think that's from only drinking 1 cup of 1/2 caff today
