Lost weight but my breast feel larger!!

Hey, so I was recently sick for a few weeks and ended up losing weight and a lot of muscle mass. So I’ve been feeling weak, but I noticed that my breast look bigger but it also feels heavy and uncomfortable. Is this due to the weight loss cause I would think my breast would shrink instead of become bigger 😩 I already had large breast but was expecting them to get bigger now that I’m in my 30s. Any words of advise would help.
