Boobs shrinking

Hannah

So I’ve been noticing recently that my boobs are significantly smaller than they had been. They were pretty big to start with, close to a D. I haven’t lost/gained any weight so I’m not really sure how to explain it. I didn’t even really notice until I realized that my bras were too big. I’m not sure if it’s concerning or just hormonal but I don’t like it. Anybody know why this might be happening? Anything I can do to potentially reverse it?
