Uneven PLZ help 😣

So I'm 17 and I just noticed that I think my right boob is slightly smaller than my left. They were sore so I was checking them out when I noticed.I have never noticed this before. I already checked for bumps and I didn't find any. I know that one boob being smaller than the other is normal but I'm still kinda freaking out about it just because I didn't notice it all before. Is it more likely that it has been this way for a while and I just never noticed?? Or is it possible they are changing now!?? 😣😔

Will they continue to get more different if that is the case??

In need of comfort or advice or something. Feeling very insecure and kinda scared.

Thanks
