Yes, perfectly normal, and that's what early teenage girls' breasts look like too. Fat deposits eventually help with the rounding out.
I have only ever taken (low dose) estrogen, no anti-androgen much less progesterone, and at 5 years on HRT I have nicely rounded mature 42DDD breasts. But even though I was a C cup at 4 months on E, they were definitely perky and conical and teenage at that point... it took years and patience for them to get the mature shape and be less sticky-outy.
I also started with some genuine gynecomastia, meaning actual glandular development, and it's very possibly the reason that I developed so fast.
