I 100% say they do get bigger, every girl who iv spoke to have and mine have as well, I found around 5/8 weeks mine seem to shrink which was obviously the swelling going and them just dropping they don’t actually shrink lol its just where they start to drop into place and tis just a shock from where they have been so high up before hand, once they drop they fluff out youl notice a difference! there are changes for up to a year xx
