is it normal to have yellow-green discharge 3 weeks after vaginoplasty?

I had vagino/labiaplasty 3 weeks ago. Discharge the first week was bloody, the second week was somewhat clear and the third week has been yellow-light green. And I am itchy. I am not red in the area, do not have an odor to the discharge and have no pain. I change my pantyliner every 2 hours and clean the area well daily. Is this discharge normal or an infection?
