Does nose tip drop after rhinoplasty?

I had a rhinoplasty done 2 weeks ago. I was hoping for perfectly straihgt looking nose. Could it be that the tip is still swollen and looks little upturned. Will it change with time and get straighter. Maybe I won't get the results I was hoping for because my tip was very upturned and that's all I could achieve with just one surgery?. Is such a radical change possible with only one surgery?
