I had five or six (I lost track of the exact number) of periods last year, which was the first year I hadn't had one roughly once a month. The last for 2007 was at the beginning of October. Four months went by in a state of equilibrium until...
... a period arrived on the morning of the anniversary of my mother's death. So the old hormones still have the capacity to respond to my emotions.
What's mildly unsettling about all of this is that in the longish intervals between cycles, I don't know what to make of fluctuations in my bodily and mental state. I notice things like an increase in appetite and wonder if it's hormonal, but then it fades away.
Before that first period for 2008, I'd had classic PMT, including a raging temper the day before (when we were packing the car to go on holidays - not a situation that's conducive to calmness anyway). But because I'd begun to think I was in menopause, I didn't cotton on to the fact that my volatile emotional state was a sign of things to come. I wish I had, it might have helped me get a grip.
I had another period three weeks after that, which was a surprise too. (Fortunately it didn't come with such extremity of PMT.)
I have to say that being in a more normal cyclical state feels better - at least, my body feels more knowable to me. But that could all be misleading - it might be months now until the next one arrives.
