How long do you wear the foam, ab & back board with your faja? BBL

My surgeon advised it would only be necessary to wear them for two weeks, then I can wear the faja alone afterwards. However after reading more into it, it looks like most people say to keep those on, along with the faja for longer. What should I do? I’m 2 weeks post op, I tried wearing the faja alone today and it made a small dent in my stomach for the few hours I wore it. I don’t want any indents..
