Prior to pregnancy I was a C cup... during pregnancy and while breastfeeding I was a D...

2 years postpartum and they are so empty if that makes sense. Like there’s just no firmness to them at all, and they have no shape to them, and they’re just so tiny and I have NO cleavage whatsoever.... i literally feel like I’m pre pubescent because I don’t even need a bra anymore. And they weren’t small before!! I don’t get it. I guess the only solution is a boob job or to just breastfeed forever 😂😭
