I get PMS, even though my meds are the same, I don't cycle, and etc. Some people will tell you that this doesn't happen, or only if you cycle your Progesterone, or while others (like myself) experience it and it is real, with no med changes. Mine can get wicked bad at times.
So, you're not crazy, or delusional, etc. Different people just experience HRT differently; not everyone's biology is going to be the same, in other words. Some people just don't, and never will, experience PMS, while others might only while cycling their meds, and then there are a few who actually have PMS. I don't know if age is a factor, but it could be also biological factors, as your body has it's own hormones and produces Progesterone and it could be producing it's own supply and fluctuating the levels like a natal woman would.
