I'm 13 1/2 months on HRT an small B Cup don't worry you will be seeing some changes.

My friend does YouTube videos, and is well 14+ years transitioned...she could go stealth if she wanted. She has awesome advice to young transitioners, so I'm just gunna drop this video here, tell you to smile, relax, it all takes time, and enjoy the ride. I hope the video helps. It's good to take advice from those who came before us, and learn to just enjoy the ride, too. Your girls will grow doll. im 13 monthes and a small c cup

I have hormones for 2 years no. I got no boobs, even no AA or AAA. Same size as male before.
But i guess i'm no example, my hormones doesnt work generally, so its only one symptome of all.
