hey hun, very early days 6 days!unders change all the time, its to do with the muscle holding the implant down, please wait until around six weeks before you decide if you hate them! lol i winged on and on on here about hating my boobs, now when i look at them they are great! i love them!
ur auntie may have had bigger boobs to start with and her frame may have been different, they can only fit what they can fit into u unfortunately! if ur auntie got to choose that will be because she either had boobs or had a wide enough chest wall to carry most sizes.
try not to flap xx
