you will get a nurse appointment and another surgeon appointment hun. have u tried the sizes on in a sports bra to see? try the rice test as well. basically 300cc is 300grams on rice. try your sizes like this to see what weight you are comfortable with. I found the rice test a huge help!
what size are you at the moment? height and weight….
im 5’3 size 8 on top, 10 bottom. im having 360 overs xx xx
