Breast growth is weird. When I started, I got a lot of throbbing and pain and sensitivity and could definitely feel the lumps behind my nipples. Then after a few months, most of that stopped and went away. Couldn't feel much behind there. But very gradually my breasts got rounder and stuck out more and my nipples got puffier. Then for quite some time, not really any change except for maybe some very slight enlargement over time. Now? I'm over a month and a half in and in February I was off my hormones for a month, and in the past few weeks I've been getting back to normal and noticed my breasts were getting a bit larger. Now my left boob is starting to hurt again and I have a hard sore lump behind my nipple again. Not sure if stopping and starting the 'mones caused it or if it was just time, but something is definitely going on with them again.
