Well, like the title says, I've started to notice physiological changes.
My endocrinologist believes in moving up dosages gradually. I'm taking Estradot 37.5 right now; I started with Estradot 25 almost six months ago. Estradot 50 will be next.
Anyways, a couple weeks ago I noticed my left nipple was sore. It sort of felt like a bruise. Since then, it's become something that I can feel under the surface. It's a breast bud! Right one just feels a tiny bit sore so far.
Also, I just noticed in the shower today that I don't seem to have dark hair around my nipples anymore. I didn't need to shave my chest at all!
So it's great that hormones are starting their effects. Hopefully even though I'm almost thirty they'll have the effect they would on a younger body. I did develop relatively late. (pubic hair at 15, for example)
And hopefully the timing of everything works too.
