I want to apologize for the pictures i posted, i thought it was okay with a link and NSFW tag 
Here is a readable timeline instead :
Starting point: No breast, no moobs, 1.3 inch areola ( 24 year old)
After 5 days : nipples were burning and errect.
After 17 days: I had terrible sensibility and soreness. Something hard started to form under my nipples (i will learn after that those are breast buds)
Up to 40 day: Those breast buds kept taking size until it reached about 2 inch or a little more diameter. The soreness went away but nipples stayed very sensible
Until now at 2 month and 3 week: I thought nothing was happening, i was wrong. One day i squeezed my breast together and noticed that my pectoral muscles had converted into breast tissues forming a cleavage. My areola expended to 2 inch diameter and my breast looked rounder. I went buying my first 36A pushup bra
I am expecting visible changes for next month
