The conti version of any HRT can cause the erratic bleeding for the first few months but I suspect you are probably not truly post meno so conti HRT isn't right for you. Femoston is a good HRT type so it might be worth trying the Sequi version ( Femosoton has the gentler progesterone) but if you don't want a bleed then having a Mirena fitted could be the answer for you. A few weeks after fitting, most women don't get any bleeding, far less progesterone is absorbed systemically and therefore less likely to give headaches and other side effects. If you then had oestrogen as gel of patch alongside this would also reduce the chance of migraines as transdermal HRT is deemed preferable for migraine sufferers.
I'm afraid many of us experience more headaches once menopause hits - with or without HRT - so it may be a matter of good pain relief when needed.
Here is the info on the Mirena:
Mirena is a levonorgestrel (type of progestogen) releasing system which sits inside the womb, gradually releasing the progestogen into the womb. It is licensed in the UK and Ireland as a contraceptive agent, for treatment of heavy periods and, from August 2004, also for the progestogen component of HRT. It can be used in both the perimenopause and postmenopause and it is particularly useful for:
Persistent progestogenic side effects from systemic HRT despite changes in type and route of progestogen.
When contraception is required along with HRT in the perimenopause.
When withdrawal bleeds on sequential HRT are heavy, after investigation if indicated. (see WHEN TO BE REFERRED )
With Mirena in place, systemic estrogen alone can be taken as the Mirena provides adequate protection of the womb lining and the estrogen dose and route can be tailored to meet the individual's needs.
Progestogenic absorption throughout the body is minimal so reducing progestogenic side effects. The effect of Mirena on the womb lining can significantly reduce bleeding and when used as part of an HRT regimen, in time, 30 to 60% of women have no bleeding at all. Although Mirena used for contraception is licensed for 5 years, the license for use for the progestogen part of HRT is currently 4 years.
