This post got missed so hopefully someone will respond. If not then I suggest reposting in "All Things Menopause" which is the most popular Meno section? I haven't really done this except when I stopped HRT (cyclical) completely for 3 months, about 10 years ago or so, and then restarted on continuous, but with cyclogest. As it turned out the oestrogen dose was too low so I needed to go back to 50 mcg patch and I didn't want to take the progesterone at a higher dose, continuously, so went back to cyclical and have stayed there ever since.
If you're not progesterone intolerant and it is the rise and fall in prog that is affecting you ( Progeterone withdrawal is part of classic pms) then why not try conti for a while, if you are post-menopausal. If you are still peri then you will likely get breakthrough bleeds from your natural cycle.
All the best
