@Pandorapitstop Thanks for asking me but not sure if I have any better ideas.
A couple of things and you hit on one yourself...
The patch dose is very high. Any reason for that? What dose did you start on?
For older women in their late 50s (you!) who are not in peri, it's more usual to have a lower dose of estrogen, more like 50mcg or 75max.
I'm older than you but even when I was your age I was never on anything higher than 2 pumps of gel - the same as a 50mcg patch. My main symptoms were hourly hot flushes, some night sweats and poor sleep. I am now able to get by with 1.5mgs, which is roughly a 37mcg patch. I still get a good withdrawal bleed each cycle (I've chosen not to do continuous and still do cyclical.)
The other thing is that Utrogestan is 'flavour of the month' but it doesn't always control bleeding enough because the absorption varies so much. It's only over the past year or two that it's been prescribed so much and it doesn't suit everyone.
The other option is the progestogen dydrogesterone which is in Femoston. This is very similar to Utrogestan ( almost body identical) and may work better. However Femoston is a tablet, so not transdermal. Unless you are at risk of blood clots, that's not an issue.
And- lastly- there is always the Mirena coil. That would probably sort it out well.
