Is it possible to hide my brazilian butt lift during recovery? I don't plan on telling anyone.

I know the first few days are the hardest and that I will most likely have to stay in a recovery home or a hotel and hire a nurse (tips, advice, cost?) I am 5'2" and 115 lbs. doctor can put 500 - 700cc's in each side so the result won't be TOO dramatic. After recovery I plan on saying that I've been working out a lot and blaming a new birth control for the growth. I am mostly concerned about hiding from my boyfriend and roommate during recovery. Is this realistic? how long will I have to hide?
