@Neversaygoodbye The main question is are you really post menopausal?
Many women assume they are, or their GPs put them straight onto combined continuous HRT.
Even after a gap of 12 months, some women still have some ovarian activity with very occasional periods and this can cause bleeding when on continuous combined types.
The guidance for combined continuous HRT is 12 months after a last period OR aged over 54 (because at 54, 80% of women are post-meno or with very irregular periods.)
The option you have is to swap to sequential HRT so you have a timed, regular withdrawal bleed. There is the option of this being 3-monthly (it's in the NICE guidance) for women who are intolerant to progesterone.
The other option is to change to a different progestogen- Utrogestan isn't always absorbed that well (but you can increase the effects by taking it with food- contrary to the instructions on the patient leaflet.)
Or to change to a patch which has Norethisterone in it, or even the Mirena coil.
The BMS guidance is there to allow options. Some women have almost no bleeding on HRT yet others can bleed heavily on the same dose.
For women with heavy bleeding, the option of 300mgs x 12 days is there, or 200mgs every day.
It is also an option for women on 3 or 4 pumps of gel (or higher).
