I actually want my butt to shrink after BBL

I had my second revision almost 3 weeks. I had it done 1/8/2018. It doesn’t seem swollen any more, but i hope it still is so it can get smaller. He added 1000 cc of fat the second time around. 700 cc first time. I feel I look wide, I just wanted a correction, not a bigger booty. Hoping it’s all still swollen. I’m a mom of 3 girls. I don’t want unwanted attention. When I measure round my hips and butt it’s 42 inches. If I work out hard, can I lose some of that fat from my butt??
