Could I have ruined my tip rhinoplasty by blowing my nose?

Hi I had tip (and a little bit lower nasal portion grafting between the holes just for balance) rhinoplasty. My surgeon told me not to blow, but rinse with salt water. I have sometimes blown the nose, as it helped me clear it, in addition to the salt water, and had no major bleeding or strong pain from it. But, could I have ruined the results ? I am a bit afraid. Best.
