Emzzy I have seen so many posts on here from people that said the same as you. They had unders and once the muscle relaxes they start to look much bigger, just look at some of the girls pics, fairy for example……from day 1 post op to now is a huge difference…….she looks amazing. I’m sure if you messaged her she could put your mind at rest.
There have been lots of girls that felt disappointed at the beginning then months on saying how pleased they are once they have fluffed. It’s very early days for you hun xx
