I've now been on hrt for about a month and my boobs are achey and slightly bigger than when I went to sleep last night. If you're considering estrogen I recommend it if you can. 10/10, coming out and transitioning has done more for my mental health and self image than anything I've done in my life up until this point.
Sorry if this is the wrong comm.
Lol I never had that experience, my nipples were sore a little sometimes but that's it.
i've talked to a few cis women who had the same thing happen during their own puberty, but it's not universal either for trans or cis women. it's just kinda common.
