nah dont stress over it....
my breasts have grown a little but still I can go out with out a bra...what im trying to say is that I will start wearing one when it will be obvious that something is there...
and the pain...dont worry its not that you ll be constantly tortured ...its just hurts a little bit , at least in my case...
right now it only hurts when I eeer squiz my nipples...so yeah ,,,dont worry...
though there are times that they randomly hurt,,,its still not that bad. ..
im two months in and even though if you look at my chest you ll clearly see a female one , they are reaaally small ,,, maybe an aa cup...
