Starshell, if you are suffering PMT and a heavy bleed, you could try a Mirena coil for your progesterone. This would mean you don't really have any systemic progesterone going into the rest of your body - because it stays localised to your uterus and is just a tiny amount in the right place. So you shouldn't get any of the progesterone side effects which some people can struggle with (like PMT). And the Mirena will also stop the bleeding, that is one of the things it is known to do excellently well. (After the first few months.)
So then you would just use estrogen in a patch or gel and forget about the progesterone as the Mirena is doing that. And you can expect not to bleed at all after a few months.
You might not want to use a coil though, and I totally get that - I can't bring myself to try it(!) - although I might if I were struggling and it was that or stop HRT.
The other thing is you could try moving to a continuous regime of utrogestan 100mg every night. You might get some breakthrough bleeding if you are still peri but it would probably be lighter than a full on bleed on a sequential regime. You could also increase the utrogestan to 200mg every night on a continuous basis. If even that doesn't help the bleeding, you might be better with a synthetic progesterone as they are known to help more with bleeding. There are some combined patches (Evorel Sequi and Femseven something or other) - they each have a different progesterone in them.
Basically, don't give up. It is just that HRT often has to be tailored to the individual and we're not all sausages in a sausage machine. Everyone is different, reacts differently to the hormones and has different needs and priorities. There is the right HRT for you out there, just experiment (without changing too frequently!!) and you'll get there!
