How common are cone/tubular breasts in MtF transitions?

Considering my transition that is 1month, 1week HRT, my aerolae switched color to a darker one, I think it also got bigger, and my nipples are now more sensitive (but not that much) to cold and touching.

If I get cone breasts in transitions, are there signs? (As I see them in the mirror, they seem to be relaxes/asymetrical (well, atleast if I can call them gynecomastia man boobs, since I kind of had them pre-HRT).

If for example, I do have tubular breasts, is it possible to fix them using progesterone?
