In the first month it felt like there was a different sensation throughout the chest area. Like a fullness, but with no apparent .....anything. Soon my nipples and areolae were tender and would increase in diameter by a 1/4 " and get puffy off and on, going back to "normal" in between. About the second or third month my breasts started budding and got even more sore and itchy. At times they were a big distraction with the ache and itch. Learned to carefully pass through doorways! In my forth month it seemed I had a growth spurt, very itchy! Gain an inch in two weeks! I'm a runner so supporting them became a must. I'm on my 8th month on E and they appear rounder and fuller, but only a "B" cup. I did go out for lunch with some other girlfriends here at Susan's and was told just the bra gave me a nice shape. My avatar is of that day and I swear I have some cleavage!
And yes, ymmv!
