Lunaception??

I looked into it at one time, because my cycles were so crazy that even regular FAM charting was impossible. I even wrote to the women who kind of "created" it and paid the like $12.50 or whatever it is for the materials. They don't print the book anymore, but she owns the copyright, or something, so she can scan and print it all for you, then send it to you.

Didn't end up using it, because needed something absolutely foolproof at that point (and no kiddos, so no worries about the Pill).

But good luck! From what I could tell, the testimonials were positive.

I did this subconsciously when I lived off the grid for a year. I noticed that my body's natural rythms started to match up with the lunar phases. It was really fascinating. I heard to practice this using artifical light, it requires keeping a light on for x mount of days, and eventually have no lights at all, (only a red light if absolutely needed for middle of the night bathroom trips), therefore you are simulating so many days with the full, half and quarter moon light and then the new moon (no light). I know you can read more about it in "your fertility signals" by winstein. That book is awesome.

it's true our cycles do amazing things! haha
