One thing that I've noticed a lot after being on HRT for over a year now, is that there always seems to be times where it is happening extremely fast, and then times where it feels like nothing at all is changing, or that it's even going backwards.
Changes from month 1-3 were rapid, then not much changed, then around month 5 I got another rapid development period, then once again it died off, then got another one around month 8, then nothing, then another around month 11, then nothing.
Just roll with it. It's a LONG, LONG, LONG process, and obsessing over the changes every single day won't do anything but cause you a lot of unnecessary stress. As long as your T and E levels are good, don't worry, and just let it happen, and it will eventually.
