Hi Emma,
I was post-menopausal before 40 due to premature ovarian failure. It is so frustrating! I'm 43 now.
I have been on a patch plus oral or vaginal micronized progesterone for about 4 years. I bled intermittently on continuous progesterone, and then had almost a year of controlled bleeding on cyclical which was much better. But I've been bleeding for the last 35! days so may need to make a change. I think mine is caused by adenomyosis.
I do think the patch can work if you can get the bleeding to be predictable or successfully surpress it with daily progesterone. (I wish there were more options other than a hysterectomy, which I'd rather not do!)
Other than bleeding, I have significant hair loss/shedding that I help a little with minoxidil. Those issues aside, I feel good in other ways on the patch - good energy, emotionally stable and healthy.
If you have POF, you might want to check out the Daisy Network if you haven't already.
