What can happen if one of my breast hasn't drained the fluid build up after breast reduction surgery?

I had a breast reduction done on 7/22/16, no drains were used and 4lbs removed. My left side drained alot the first 4 days after surgery, but my right side still hasn't drained, and I can hear the fluid sloshing when I move. I've asked my doctor at the last two check ups to please drain it but she said that I could get an infection if we drained it and that I need to give it more time, and that it should absorb In to my body. Sounds crazy to me, plus it's so tight and uncomfortable. Please advise??
