Hey GF, have faith in your pains! They ARE doing something! The stupid measuring tape is evil, I tell ya. I think we should only measure every two or three months. Anything more frequent than that is just too inaccurate and discouraging!
It's taken me 6 weeks of daily pains to get that half inch back that I lost last November. Our breasts ARE growing - it's just frustratingly slow for us smaller gals. Like you said, I too notice that when I lie down, they don't totally "disappear" into my rib cage like they always used to. And there is most definitely more to grab; especially at the tops. It's "beefier" up there.
I find myself a little discouraged when I look at myself in the mirror straight-on, and they don't look much different than before; but there's no mistaking the fact that there is a lot of fullness there that didn't used to be there. If I put my arms down at my sides and kinda "squeeze" my breasts together with my upper arms, there's this lovely cleavage that appears! That can ONLY be there because it's more dense and filled-in inside my breasts.
The past 6 weeks have taught me that permanent breast growth is totally possible for me; it's just gonna take a really long time. Like maybe a year to a year and a half to get up to a B cup. Even on BB's website they said the average rate of growth is one cup size every 3 or 4 months. So that's like .25" a month; which is just the AVERAGE growth. Some grow faster; others, like us smaller gals, seem to grow slower. And sticking religiously to your routine is a must! Since you are noticing definite fullness, whether is shows up on the measuring tape or not, that is GROWTH, girl!
I know, for me it seems like I'm in so much pain all the time, that I should be a D cup by now; but I'm still a AA. Granted, I'm a fuller AA than I was a couple months ago; but still, I was expecting to be a little bigger than this by now. I hope to fill in my A cup bra by July, maybe; that's how long I'm figuring it'll take.
Something else that seems to keep the pains going is thinking about your breasts growing, as often as you can throughout the day. Like every time you eat, say to yourself (in your head, so other people won't think you've lost your marbles, lol) "All this nutrition from this food is going straight to my breasts, and will help them grow." With each swallow, imagine there's these tiny little vitamins going into your breasts and making them expand and get larger. And also with each protein drink, and each pill you take. Same thing when you shower, or massage: imagine all the blood vessels getting warm and the blood flowing like a river through them; and again, that your breasts are expanding. When I fall asleep at night, I tell myself that my body will be concentrating on growing my breasts while I sleep; and again I imagine them getting larger. If you get your mind on the "Booby-Growing Train," it'll follow up with growth.
You've got a great program; keep it up! I hope the dietician will have some suggestions to help you put on a little more weight.
