Is slight fluid retention after JP drain removal something to be concerned about? (photos)

I'm 24 years old and on the 30th I had a Fleur de Lis tummy tuck. So far I have had a speedy recovery. Little to no pain at all. Most of my discomfort was from the drains. I got the drains out last Thursday since all were under 25cc's for 48 hours consecutively. I noticed a few nights ago that my tummy on the lower left side and my right hip, when I lightly pressed on it the skin retracted somewhat slowly. No pain associated with it, it's not warm to the touch. Should I be concerned?
