Hi Donna Suzanne
The good news is you can continue to use cyclical HRT for as long as you want provided you haven't any medical reason why not ( eg endometriosis), or maybe large fibroids.
Although Femoston has a better tolerated progestogen than Trisequens (which contains norethisterone that causes problems for some women and as it is derived from testosterone can cause androgenic effects such as hair loss), reducing your oestrogen dose to 0.5 mg from almost 2 mg on average throughout the cycle is a drastic reduction, let alone the change from cyclical to conti - which can lead to continuous progestogenic side effects.
When changing HRT types it is best to change only one thing at a time - in your case the progestogen - and take it cyclically to see how you tolerate it. Therefore I would recommend Femoston 2/10. This will give slightly higher oestrogen as there are no days with a 1 mg dose as with Trisequens. You are still below the average age of natural menopause and nowhere near 60, so no problems with continuing with 2 mg.
Vagifem will help with symptoms of vaginal atrophy due to reduced oestroen but not all the other menopausal symptoms. I would go back and say you agree with the type of HRT, but not the dose/conti part of it. Say you want to continue with a cycle and would like to continue with more or less the same dose of oestrogen that you have been having and therefore ask for Femoston 2/10. If you are still peri-menopausal then cyclical HRT is definitely advised. Unfortunately Femoston conti does not come in a 2 mg dose.
Good luck and keep us posted - no need to be terrified - just assertive with your doc, and read as much as you can about menopause and HRT types!
