The release of yellow snot during a minor ablution (Wudu)

I often get yellow snot during the small ablution when I blow my nose. I know that a simple transparent slime is not najas. But pus, according to most Muslim scholars, is najas. Why am I so worried? Yellow and green snot are most likely purulent. However, I have no malaise, high fever, pain in the sinuses, which means there is no inflammation. I have allergies, and now spring is the period of allergy exacerbation. I do not know if these snot secretions contain pus or not. What should I do now, when such secretions come out during minor ablution, should I perform minor ablution again or not? Are such snot najasa?
