I hate my boobs!!!

Before I got pregnant I was a DD. I'm only 5'4" so that's already a big size but especially for my height. Now they're at least a size bigger and I'm only 18 weeks! They're so freaking big and get in the way and they kill my back and I'm just so sick of it! I just want Bs or Cs again like when I was in early high school. Anyone with big boobs end up having them shrink after breast feeding? Did they get smaller than originally, back to the same size, or stay big? I know everyone is different, just trying to see if there is any hope!
