Abdominal Swelling After Leg Liposuction

I have had Liposuction for the whole of my lower limbs (thigh/hip to ankle) done in 3 separate operations within 4.5 months (Dec 08 - Apr 09). The results are great, and I'm now a UK8/10 all over. I'm healing well, the swelling is reducing on legs, some still remains but as expected. However, I have abdominal swelling/bloating and look pregnant, as well as slightly swollen on my boobs and face/neck/buttocks. My body seems to be retaining fluid all over, although doesn't seem that much on legs. Is this normal after 7 weeks since last op?
