For all of my back issues and even my knee replacement, some surgeons said 5 days , and a couple others said 3 days to be off before surgery. So its out of your system, at least in regards to surgery, pretty quickly. I had no bleeding issues post 2 spine surgeries and a knee replacement. But double check with your PcP or Hematologist to be sure
When I had my PE my Hemoglobin and Hematocrit were so bad, they took blood and it coagulated by the time they got it to the lab and that was in hospital.
