Deflated breasts

So for the past few months I’ve noticed my boobs have been kind of deflated, for a lack of a better word lmao. They’re smaller and saggier than they’ve ever been before. I’m only 20 but my entire life before every period they’d get insanely swollen, which would hurt like a bitch obviously but I at least felt sexy and fertile because of it. At their largest they were like Ds but now they’re Bs. I did some research and found out this could be due to hormonal changes but I’m not sure what could have caused that. I was anorexic in 2018-2019 and also read that could cause saggier breasts, but it’s weird because even during that time when I was emaciated I remember still having larger boobs that would get super swollen. Now I wish I still had that problem. I don’t get wet as easily now either, which might be totally unrelated but it doesn’t seem coincidental.

Does anyone else have this issue/advice/tips?
