Boob shrinkage

So I have always had very small boobs - 32/4A cup - but since stopping breastfeeding two months ago I swear they have shrunk to even smaller than they were before pregnancy and I absolutely hate how they look, feel like a child. Anyone else had this? Does it get better again somehow?! Presumably nothing I can do (except a boob job which I don’t think I could face)? Thanks x
