How long does it take for bloating to go away after breast augmentation?

I am very fit and athletic. I went into surgery weighing 119 lbs with very defined abs. I am 6 weeks post op from breast augmentation and my lower abdomen still looks bloated and feels swollen. Is this normal 6 weeks out and what is the normal range for abdominal swelling? I started going to the gym last week, week 5 but am only doing low impact cardio (elliptical) and lower body exercises such as squats.I love my augmentation results but the bloated feeling / look is driving me crazy.
