Bleed 12 days post op

I had a tonsillectomy and adenoidectomy on July 31. I sneezed this morning and blood came out of my nose. It wasn’t a lot, I cleaned it and went back to what I was doing. I stepped outside for a bit and started coughing up scabs and mucus from my throat. No blood from my throat, but my nose began to drip blood. The bleeding has stopped now, but is this a concern? Do I need to go to the doctor, or am I good since I stopped the bleeding?
