Hey,
that's very good news that your husband saw the difference! Besides, he doesn't know that you're noogling, so this is the proof that it does something for you! We see and feel our breasts every day and are so focused on it, so I guess it's normal that you don't notice every difference in growth yourself. Even if you take pictures, I think it is difficult, because you have to make sure you take them always in the exact position. Yesterday, I tried taking pictures of mine and I must say, they didn't look like when I see them in the mirror. They looked huge! But when I took a picture from another position (1m further) they looked smaller ..... which is obvious.
Anyway, you look great in that pink bra! The swelling you got is very noticable! In a couple of months this must be permanent, don't you think? I also think it is good to try to noogle your smaller breast a little longer.
