3 weeks post breast reduction. How long does swelling take to go down? How much should go away?

I had a breast reduction done on 06/20, No drains. I was a 34DDD, about 1 lb removed from each breast. I was told I have very dense breasts. Post op I'm a 34DD (all of my old 34DD bras fit). My back still hurts. My PS said he was going for a C cup & I don't see the swelling going down 2 cup sizes. There's barely any redness or discoloration. I don't want to be a DD or D cup at all! I spent most of my life a C cup even with weight loss or gain (5'5/107-130 lbs) until 23 when they grew. I'm 26.
