How soon can I get my second BBL and do most women get 2 to get the best results?

Had my BBL Jan 9th. I'm losing volume in the butt, my doctors only did 700 cc of fat. I wish he would of done more. Will he do a revision for free if I'm not completely happy? Also I'm suppose to get a tummy tuck later. He said after about 3 months. Can I do a tummy tuck and a second bbl at the same and if so, how am I going to be able to rest and recover since I can't lay on my back or stomach?? And do most women get 2 BBLs to get the best results ??
