There should be someone along soon who knows a lot more about HRT than I do, but in the meantime I'll offer a few thoughts.
If you are taking hormones without a doctor's supervision there is not telling what results you will get. And if the hormones are black market or internet, there is no telling what they really are.
My T levels were normal for a male. Even with T-blockers, any breast growth in the first three months was mostly in my imagination. Now, after almost 11 months I fill an A cup plus a little extra. I think it takes a while for something to happen before there is actual growth. (I saw it explained once but don't remember the explanation.

)
If you are at all concerned about health risks – as you should be – please see a doctor to supervise your hormones.
And not everyone can grow breasts – it depends on the receptors in your tissue.
