I was a 12DD before I fell pregnant with the twins, then went up to a 14E. When I lost my milk I h=then went down to a 10E, so I lost the baby weight, but not cup size.. This time around I was a 10E before pregnancy, went up to 14E and now I'm back down to a 12DD so I'm back where I started.. I am still Bf so have no idea if they will shrink further.. I really really hope not!!
