Girl I started with 32B and had 450cc and now measure at 32F. I know what you mean though, I’d like mine to be a bit bigger but I think you starting off so small they wouldn’t have been able to go much bigger anyway. Don’t feel like you wasted your money, look at pre op pics so you remember how much better they look now. Do you have any pics? I’m sure they look great! Plus at 3 weeks you’ve still got dropping to do. Wait until at least 6 weeks and see how you feel then xx
