Uneven buttocks after more fat was injected to fix unevenness

I had a 2nd bbl surgery 2weeks ago because my right cheek was bigger than my left. He added 400ccs more in my left then my right cheek it was even and overnight my left became bigger now I'm worried because more fat was injected their. I haven't sat on it or laid on it at all is their anything I can do to make it even? Please help...
