Normal for Rhinoplasty Swelling to Increase Suddenly After a Month?

I had a Septoplasty , and turbinate reduction for breathing improvement, from esthetic point I had a hump reduction , Osteotomy for my wide nasal bridge , and minimal tip reduction. The doctor mentioned I should expect 80% swelling reduction by 1 month and the rest will continue for 6 month to a year, everything was going fine , by the 5th week I noticed a gradual increase in my swelling to my bridge and the tip to a point It is difficult to laugh. Is that normal, what can increase the swelling and should I do anything about it.
