Pamela, it was interesting reading your report and progress.
being intersex, my experience is entirely different.  I just started HRT (Patches), and am barely into my second week of it.
Most of the changes you experienced, happened to me over the last 2 to 3 years without any additional estrogen.  My penis shrunk to about two inches, and my testes are the size of a hazelnut, but extremely sensitive against touch (they hurt badly).
My breasts are now between an A and a B cup.  I have another advantage over "normal" trans women and cis women, I do not have body hair, not on my legs, chest or under the arm pits.  I also do not have an Adams Apple and because of this not a very low male voice.  My "normal" voice is in the androgynous/low female range, and my beard growth is not very strong.
I have no idea what estrogen will do to me, and what changes I can expect at which time.  So far, I do not feel anything that I could attribute to estrogen.  It is just amazing that the stuff works so different with different people.
I wish you continuous good luck on your exciting journey!
