i don't think boobs stop growing after your first period, i know mine didn't, and i've actually lost weight since then and have no need to be on birth control. mine seem to have slowed down in growing since last year, but if boobs generally stop at 18 or 19 maybe i'll end up bigger than a c cup. oy...
When I started taking the pill they grew a bit, but now it's been a while I'm taking and no sign of growth. But I'm still hoping they are gonna grow some more. They have to, goddammit! hehehe..... Love, Louise.
Oh, I forgot... they started to grow when I had my first period... So, I guess that's just in theory.
I was in my late 30's and mine still grew. I have to say I don't think they ever stop completely as some of it comes from gaining a losing weight as well as there is fat in your boobs as much as it is anywhere else in your body. Love & Ideas EnonEmouse
