I was tested covid-19 positive on 4th of may with no symptoms, home isolated without steroids and oxygen support. Now I have mild fatigue with mild cough or (no cough) had congestion for two days, with Montekulsta for 10 days I do not have any breathing issue as of now, whenever I take steam inhalation I get white clear phlegm with black streaks (no phlegm without steam inhalation) from 2 days, with no other symptoms, with modrate sugar level 158 after food, please suggest if  I should go for any test to be sure of black fungus infection..
