How long until swelling goes away? When can you get a good sizing done? (Photo)

I had my breast reduction done 2 weeks ago, I was expecting them to be a lot smaller as had done for back problems.. Asked for a b small c... Which is what doctor says she has done but went and got a measurement done (I know there would still be swelling) but how long before you can tell your correct size.. Hoping they aren't going to still have an impact on my back if they stay large still
