The latest guidance from NICE says that in peri you can have a 3-month cycle, so that means taking it for 2 weeks out of every 12.cks.nice.org.uk/topics/menopause/prescribing-information/hormone-replacement-therapy-hrt/

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.
Note: the absence of bleeding whilst taking a cyclical regimen reflects an atrophic endometrium.
Exclude pregnancy in perimenopausal women or women with premature ovarian insufficiency.
Check compliance with therapy if the progestogen component is taken separately.
If HRT was initiated in the perimenopause, consideration should be given to switching from monthly or 3-monthly cyclical regimens to continuous combined regimens after the woman becomes postmenopausal.
Most GPs won't offer this, (it has been used privately that way for years often with access to a scan if there is odd bleeding that needs checking out.)
