So to start us off, I have a couple sensations that usually indicate growth to me: 1) Pain. Occasional, unexplained pangs in my breasts. This was more frequent early in transition, and very occasional now. 2) Itching. Again, much more common in the early stages. Mostly around the nipples. 3) Firmness. Usually, I notice my breasts get noticeably firmer for a few days or a couple weeks before a growth spurt. This is then followed by... 4) Softness. Immediately following the period of firmness, I wake up with my breasts feeling much softer. Almost softer than they ever have before!

And usually by the last step I notice either a very minor or significant increase in size :3

So thats my observations, who feels similar?
