After a hysterectomy, your cycle should be flat. There are mail order saliva tests. They are not as accurate but lacking ovaries should mean you don't have wild swings. If you did a few saliva tests at the various days and times of day, you may find a problem. An integrative medicine physician may be helpful. Google "saliva hormone testing for women" and you will find lots of in formation.

Adrenal fatigue, cortisol dysfunction and other hormonal issues can all contribute to your struggles.

I understand the difficulty finding the right doctor when limited to a government based/directed health plan. The US Medicare system has many of the same barriers.

My best to you.
