[Sincerely Yours ♥]

Hi there. Fourteen years old is actually still very young. I can assure you that you will grow much more in the upcoming years. I wouldn't worry about it.

However to actually answer your question, I know birth control pills can contribute to breast growth, probably due to the hormones. I went up a few sizes actually since I started taking birth control last year. There is also surgery, but that's definitely a last resort & must be when you're done growing.

Again, you are very young & you will continue to grow for many more years. I wouldn't worry about it.
