My breasts did grew over years but like milimeter per year probably. -_- I was completely flat when I got my period, they started budding late.
My aerolas are puffy like in underdeveloped breasts but the breasts are round.
May be weird but they look a little bigger after weight loss lol.
Anyways, hormones:

07/21/2014.
FSH - 5,1 IU/L
LH - 12,6 IU/L
Beta Estradiol - 212 pmol/L
Progesterone - 8,2 nmol/L
Prolactin - 140 mIU/ml ( the m is a letter I can't find on my keyboard lol)
Testosterone - 1,5 nmol/L
Cortisol - 276 nmol/L

I am confused about this beta estradiol, is it just a part of overall estrogen?
My period started 6 days after this test.
