Boob shrinkage.

So I breast fed my baby for 7 months. Exclusively pumped and nursed for the first 3 months. I have stopped due to low supply and just being tired. (I know sounds lazy but atleast I got 7 months worth in!) my boobs before and during pregnancy and breastfeeding were around a size c cup. Since I've stopped they have shrunk down to nothing! Just an A cup! I am so sad and not happy at all with them. They feel small and just empty. I really hope thy don't shrink for the next baby. :(
