I am a 23 year old female. When I was 18 I went on Loestrin
24, and my breasts
got bigger but a cup size, maybe even 2. I was so happy. They stayed pretty big, wavering depending on my weight loss or gain, but overall I stayed around the same weight (I never actually lost/gained enough to change dress sizes).
However, now that it's been 5 years since I started on this pill I notice my breasts have actually gone back down to what they were originally. I am so upset!
