My swelling in my torso has increased from weeks 4 to 6 post-op of tumescent liposuction. Is this normal?

I had a BBL on 2/27 with full torso lipo, including upper arms and inner thighs. I know swelling is still present since I am only 6 weeks post, but it has changed from hard bands to soft, subcutaneous swelling. Sometimes at the end of the day my abdomen moves like a waterbed. I was 168 pre-op, then at week 4 I was weighing at 157 and very slim. I am retaining more water and am back to 161 or 162. When will my body release the water? I am concerned because sometimes it feels like loose skin.
