I've shrank from about 5'5 3/4" to 5'4"

I'm only 29 btw and been on HRT for 5 months. That means somehow I've shrank nearly 2 inches in 5 months or so. I noticed this when looking slightly up at a co worker today who used to be my height. Also, a girl in school who is not much shorter than me, told me she was 5'3" and I was thinking "no way" ... The only thing I can think of is posture? Perhaps the tendons in my hips shifted the way I stand, but I'm seriously trying to stand up straight as can be! I do not think my bones shrank in any way, as I've always thought that to be impossible short of having osteoperosis.
And honestly I don't want to shrink.. 5'6" was fine with me, now I'm approaching being short even for a girl...
As far as shoes, they've been a females size 9, and honestly I could probably squeeze into an 8.5 comfortably and possibly into an 8, when in october the size 9 was right where I needed to be.
IF ONLY MY FACE WOULD CHANGE LIKE MY BODY!!!
