One month after fat grafting and it is all gone! Was I undercorrected? Can I get fillers (Juvederm and Voluma) in two weeks?

i did fat grafting 4 1/2 weeks ago and i am comparing before and after pictures of fat grafting on my cheeks and jaw. i look almost the same as before and perhaps a little thinner if that makes sense. the swelling seems completely gone (i only looked slightly swollen for a week). i want to do fillers (juve and voluma) on my temples, syubmalar and jaw in two weeks. is it possible the fat was already excreted after one month or was i way undercorrected?
