Breast growth

I started HRT two years ago with 6mg EV/day sublingual, 12.5mg cypro/day. I had tender breast bud growth that eventually went away, and really kind of maxed out at basically AAA little breasts.

Because of supply issues and costs, I recently switched to 4m EEn/7 days subq, 200mg progesterone suppository, no AA. I have been on this schedule for roughly a month now.

I have seen a very noticeable growth of my breasts since starting this dosing schedule and method. But I have also experienced the return of the budding tenderness, and seemingly an increase in sensitivity of my breasts. It has not become uncomfortably severe in any way, but it is very much noticeable, especially during the morning shower.

My question is: is this to be expected as far as the suddenly resumed tenderness? And should I expect it to continue until my genetics max out my potential breast growth? It seems anecdotal that the prog kickstarted my growth again, and I am not complaining about it, just curious if it is normal.
