avoid having a hysterectomy

I have recently been diagnosed with adenomyosis alongside the endometriosis which I was diagnosed with ten years ago. I am 42 years old and at a high risk of osteoporosis so I am trying to avoid having a hysterectomy as I would then have to be put on HRT to help prevent osteoporosis but that has oestrogen in it which could make the endo worse (endo can carry on even after a hyst). I have been put on the progesterone only pill Cerelle and the idea is that if it works I will be on it 8 years so I can reach a natural menopause. Is there anyone who has managed to avoid having a hysterectomy? If so, how did you cope with and manage your symptoms?
