I could offer some insights, but it's without knowing what stage of meno you are at etc @bellabride
Evorel and progesterone daily is for women post meno (no period for 12 months) and although some bleeding is normal for a few months on a continuous regime, it's usually just spotting or very light bleeding.
Are you actually post menopause (were you when you started this combination?)
If not, you ought to be using a sequential regime of 12 days Utrogestan each month with a predictable bleed afterwards. (You can still do this type post-meno. I've done it that way for years, for various reasons, with my consultant's guidance.)
If you change to MPA, that's Provera instead of Utrogestan.
Statistically, if you want that facts, MPA is linked to higher cases of breast cancer (still very low, but higher than Utrogestan.)
The progesterone in the Mirena is still a synthetic one, but may be slightly safer.
Have you tried using Utrogestan vaginally ? That can help absorption. If you are using it daily, it may not work (needs to be inserted after sex) but it might be an option.
It's used that way in Europe and in the UK as a fertility drug, but not actually licensed as HRT by that route. But again, meno consultants prescribe it that way.
