Hi Nici-j
I am one of those older women on cyclical regime - I'm 71 and I've been on cyclical HRT more or less all the time since 2007. Firstly standard 28 day cycle and then after a blip extended the cycle to two-monthly with agreement from my gynae GP locally. Now down to 5-6 weeks due to odd episodes if unscheduled bleeding.
It is doubtful that your GP will recommend monitoring scans in the absence of any symptoms to indicate a potential problem. The pathway for this is quite strict. The times I have had scans and hysteroscopies have been when I've had spotting at the wrong time, and the scan has revealed a thikcened endometrium but no issues other than that.. A couple of times I have had a private scan but those for whom this is an unaffordable option it is fine to continue without them, say, if on a 6 week cycle but report to the doctor ANY issues of unscheduled spotting or bleeding.
Having said this the recent BMS detailed paper and guidelines about endometrial thickness and HRT, does I think recognise that older women may still be in cyclical HRT and do have a pathway for such cases (of unscheduled bleeding) . Whether GPs will follow it or not is another matter but it;s as well to have a look.
https://thebms.org.uk/wp-content/uploads/2024/07/01-BMS-GUIDELINE-Management-of-unscheduled-bleeding-HRT-JULY2024-A.pdfHave just checked and there are major and minor risk factors (for endometrial cancer) identified that need to point to investigation being needed, in cases of unscheduled bleeding . Major risk factors include being on 3 monthly prog cycle for more than 12 months, or cyclical HRT for more than 5 years if over 45. You would need to read the key messages.
You haven't said what your oestrogen dose or delivery method is? Also be guided by your withdrawal bleeds. If you are taking the licensed dose of progesterone and not getting much of a bleed the likelihood is that you are mot building up much endometrium (this is my case - on a medium dose of oestrogen), provided you're absorbing the progesterone adequately.
