@Sidge Just dropping by to explain....the 3-month regime is in the NICE guidance, as being suitable for all women, in peri or post menopause.
There is also a tablet form of HRT called Tridestra, that is 10 weeks estrogen-only then 14 days of estrogen+progestogen.
I was started on exactly the same regime as @Kat2106 Not the spray, but gel. I was on a 3-monthly cycle from a specialist for years.
NICE
Regimen
The hormone replacement therapy (HRT) regimen used depends on whether the woman is perimenopausal, postmenopausal, the route of administration, and the woman's wishes.
Combined HRT can be prescribed as a:
Monthly cyclical regimen — oestrogen is taken daily and progestogen is given at the end of the cycle for 10–14 days, depending on the type of progestogen. The suggested dose of progestogen given in a continuous combined HRT regimen is a minimum of 0.5 mg/day of norethisterone or 2.5 mg/day of medroxyprogesterone acetate.
Three-monthly cyclical regimen — oestrogen is taken daily and progestogen is given for 14 days every 13 weeks.
Continuous combined regimen — oestrogen and progestogen are taken daily.
For perimenopausal women, monthly or 3-monthly cyclical regimens may be used.
A 3-monthly regimen may be more suitable for women with infrequent periods or who are intolerant to progestogens. See the section on adverse effects for more information.
A monthly regimen produces monthly bleeding whilst a 3-monthly regimen produces a bleed every 3 months.
A continuous combined regimen is not suitable for use in the perimenopause or within 12 months of the last menstrual period.
For postmenopausal women, monthly or 3-monthly cyclical regimens, or a continuous combined regimen may be used.
