It's been almost a month since I had a septorhino, is it okay if I'm jumping? Will that effect anything?

That should not affect greatly too much accept that you may notice some increased swelling at this time. Usually by 6 weeks you are good to do whatever you want, but on this you should ask your surgeon because nobody really knows what was done accept you and your surgeon. There may be situations that your surgeon would say for you to not be doing that right now, and none of us could possibly know that. Best of luck. 

Recovering from rhinoplasty is a healing process. Part of that process is restricting yourself from strenuous activities that might potentially injure your nose before it is healed and strong. Most patients do a great job about protecting their nose. Accidental bumps rarely cause any injury. What I worry about is other people who are not aware of your healing nose. Sports and crowded events have the potential for someone to accidentally injure your nose. I would continue to avoid those places while healing. Talk with your surgeon so she/he can keep you on track for safe and happy result. Safety comes first.
