Now, Im not on actual HRT as you think of it, but I am on something that is affecting me...
with that being said... yes, i see what you are saying and Ive never had it explained to me like this before...so here goes
I started tracking my thoughts, feelings, libido and aspects of transition in a journal. I also started comparing that journal to the female monthly hormone cycle which you will find here:
http://hormonehoroscope.com/the-female-hormone-cycle/now you will see that a female hormone cycle has rises and dips in estrogen, testosterone and progesterone...
my moods, thoughts and feelings follow this nearly to perfection and I notice when T rises, I see and feel more "manly" if you will. When E is up I feel and see myself so feminine that it amazes me. I also notice during the high T phase, my body and face hair is more prominent. I have been wondering about this for a few months and started checking this for the last month and a half. I wonder if what you are describing is actually your natural flow of hormones affecting what you see and feel. I have days when I think Ive completely fell off the wagon and back a step and then BAM, I have a breakthrough where everything moves ahead 3 steps... then I drop back one or two... these occur in the same timing as hormone drops or peaks. Maybe try mapping it and see. I now know whats coming to a degree and Im think after a few months I will know my cycle perfectly and can predict what I will feel like and what days will be good or bad so I can prepare
