I had Septoplasty/Rhinoplasty 3 weeks ago. I know it is early, but should my nose look this asymmetrical?

After a rhinoplasty it can take several months for the swelling to subside and you may not realize the final shape of your nose for up to 12 months. It is too soon in your convalescence to determine the final shape of your nose. Give the swelling time to evolve.

Although there is some asymmetry in the tip and alar margins, this could be from normal post operative edema. Don't be too concerned about this now, and follow up with your surgeon at timely intervals every 3 months or so. Final results could take 1 year or more to be evident.
