Breast Augmentation 4 days ago. Fluid in breast, trickling feeling?

I had my breast Augmentation 4 days ago. The 1st day no fluid feeling, 2nd day was tolerable and now I feel the trickling/moving fluid feeling everytime I take a deep breath. If I lay down and sit up it feels like quite a bit moves from the top of my breast to the bottom but also feels like it stays gathered behind nipple. There is little/no bruising. And it doesn't feel like there is any part bulging. What could this be? There is a bit more swelling in this breast but it had more swelling to begin with.
