Whatever you do, I think you need to make one change at a time so you have a better chance of knowing what change has impacted what. Not sure what benefit you think there might be to taking utrogestan alternate days, if anything I would have thought that is more likely to cause spotting than daily.
I empathise with how you are feeling tho, I still feel like I am chasing my tail with hrt and given tests are unreliable there is no clear path to knowing doses aside from trial and error. You do need to give each change time to take effect though and, as I said, only change on thing at a time.
