Hi,
By no means am I an ‘expert’, but been on the ole HRT about 6 years.
You seem to be on quite a low dose of oestrogen - which is fine if it controls your symptoms, but I wouldn’t imagine much endo has built up to come away in a bleed.
I would just carry on with your prescribed cycle (presumably 14 days of oestrogen only, followed by 14 days of both, then straight back to 14 of oestrogen and on and on…….. for ever (:.
Some ladies do not get bleeds on sequi, they miss some but I think most do- you might have one next time . So, I would go on for say 3 months and if still no bleed then go back to your prescriber. Hope helps.
