HI all. Thanks for your replies.
I definitely ovulated. I am one of those who suffered quite severe pain during ovulation, especially on my right side and I have that at the moment. I also got the jelly plug thing come out, plus some egg white type stuff a couple of days ago, so there's no doubt.
I guess there's not much point continuing to ask questions if I can't even be believed here when I share what is happening to me. Don't forget, a lot of us have been abandoned by our doctors so it is rather depressing not to be believed on a forum like this too.
To anyone else who might have stumbled across this post looking for help, I suggest you google the term 'ovulating after menopause'. You will find it is NOT uncommon. Also, natural progesterone seems to help lots of women. I just don't know if it might have been the cause of my ovulation, which is what I was asking about, but what DG said makes sense, so it could be down to that.
Thanks again.
