I've been having an achey bone sort of discomfort in my pubis the last few days, I know I've had it before but can't remember when or why (possibly during pregnancies). I've done some reading and it looks like the hormone relaxin may be the culprit and the production of this increases during ovulation and pregnancy and can get a bit erratic during menopause, so that would explain the sudden occurence. It basically seems to relax the ligaments that hold the bones together (so you can see the logic of it for ovulation and pregnancy). Apparently if you get uneven relaxing of ligaments in the pubic bone area, and one side moves more than the other, you can get pain there. I've also got REALLY sore boobs and nipples at the moment, so I got all excited thinking I might be pregnant (I've read that on rare occasions this can happen after starting HRT) but I've taken a test and I'm not. Sadface, but I actually didn't really think I was.
