Hi Robin
It does sound as if your sympotoms are hormonal and in which case ADs are not really indicated - but I understand your problem with progesterone and synthetic progestogens - there are quite a few women on here who are either intolerant or prefer to take them as little as possible!
If you started missing periods 6 years ago then it is very likely you are past or very near menopause by now - it doesn't usually last that long from the start of missed periods. The periods getting close together is a classic indication of the late reproductive stage just before peri-menopause and that sounds like some time ago.
As you have had an ablation - are you able to take less progesterone or perhaps have a longer cycle than the rest of us with intact wombs? That would be ideal for you if possible and something to explore with your specialist when you see him/her.
It does sound like your depression/anxiety were/are hormonal if you suffered from reproductive depression ( ie PMS and PND). Have you seen the work of John Studd who has researched and treated this using high doses of oestrogen? There is a lot of info here:
http://www.studd.co.uk/reproductivedepression.php. The main pages on different types of depression are on the left but lots of pages in each section on the right. His regime consists of usually 3-4 pumps of oestrogen gel, a blob or so of testosterone gel daily and for progesterone intolerant women 7-10 days of vaginal progesterone per calendar month - but such a low dose of progesterone would need medical supervision because of the risks of endometrial thickening and potentially cancer - but not sure how having an ablation is affected by this? You would be advised to have regular scans on this regime - so this is something to mention also to your specialist.
Yes testosterone improves mood and energy levels and helps with muscle aches and pains as well as libido - but not for everyone as it depends on the reason for your symptoms. Also it is best to make sure your oestrogen levels are good before or at least at the same time as introducing testosterone.
Hope this helps
