tip for baby tgirls just starting hrt: the doctors are lying to you your boobs will keep growing well past 3 years, 3 years is just where the studies run out of funding.
i am nearly 5 years into hrt and i just had a growth spurt that brought me up another cup size, and i've heard similar experiences from people 10 years in.
it'll take a while but your tits will keep growing, it might take a while but you don't have to be anxious about them stopping (especially if you eat well enough so your body has material to grow them with)
