HIya hun, it can take a full year to drop and fluff completely so there still lots of time for change! Also, no one has perfectly symetrical breasts, some ladies diffences are only slight but they are there. When your small chested the differences are far harder to notice, a BA can not change the shape, height, nipple postion ect it only enlarges what you all ready have to any differences in the breast become more noticeable. It’s 100% normal and it affects almost everyone, it’s best to think of your breasts as sisters not twins! Happy healing and I hope this helps x
