Oh yes! I'm 52 as well and my weight bounces up and down by 10 lbs over the course of a week. And a recent overnight gain of 7 lbs. blew my mind!
Then there's the "grand announcements" of bloating and cramps, and then no period actually happens. Weeks go by, and just when I've given my last stash of tampons to a friend, my period starts without notice.
We should be able to get medical marijuana for this!
