Am sort of operating in "safe mode" as the hormones start cresting. Though all my life I've been on a 21-24 day cycle (save for the year or so when I was training for the Tour de France. Then, it was a roughly six-week cycle), am still neither used to or happy with it. Wish it didn't have to be as physically painful as it's always been. Wish I didn't have the 2-3 days of utter hopelessness that show up before the bleeding.
The Change can't come soon enough.
