I began to have breast growth from prescription meds. I then started taking estrogen and saw more growth. Then I began using progesterone cream on my breasts in addition to the estrogen. I don’t think it did much as far as actual breast growth, but my areolas got bigger and my nipples got so big that I stopped using the progesterone after about four months. I’m still taking the estrogen, and the past few months I’ve had a major growth spurt. I’ve thought about stopping the estrogen as I never expected to have breasts this big. Even under baggy shirts they are very noticeable. But stopping isn’t easy. Now that I have breasts, it’s almost like an addiction, as well as a huge turn on, wanting and needing to see how much larger they can get.
