Hi Beth,
It's so funny that you should bring this up. I most definitely have a "period" or mood cycle. For me it's in dramatic contrast because I give myself a single shot of estrogen once every 4 weeks like clockwork. In fact, I have a clock in my home that tracks the phases of the moon, and because I was born on a new moon, long ago I made the decision to synchronize my hormone injection to the new moon.
When I was younger, I did deal with severe depression, which I completely resolved 11 years ago with a powerful form of meditation. But it's pretty typical in the last 4 to 5 days before the new moon for me to get bloated, tired, emotional, mildly depressed and cranky. At the new moon, I give myself a shot (OUCH!) and within a few hours to a day, I'm totally fine.
My spouse also appreciates having a clock in the house that displays the phases of the moon; when I'm cranky, emotional and complaining that I'm fat, she knows to check the clock so that she can remind me that the new moon is in a couple of days, or whatever.
I would say yes, I most definitely have a cycle; my cycle is tied to the new moon; and I find that my cycle is in stark contrast because my hormone injection happens once a month.
Peace,
Miharu
