Essentially your body will also tell you, i.e. DO NOT IGNORE THOSE SIGNALS!
Sport, and sport, and then some, it all depends. Would I even today 1 year post-op and 1 month post-labiaplasty sit on bicycle? No WAY José!
Walking, yes, definitely recommended - but not everyone would say WALKING is 'sport'.
Light exercises, so long your body does not object is a good thing - in my experience.
Take care,
