Pulsoksymetr, opinions and questions

Hi from 4 incomplete days I am going through covid, I would like to ask if it is normal to saturate 95-100, feel shortness of breath or such discomfort? Or it is an exhaustion fever which in the first days was 37.2 the next already 38.5 to 39.5 , today the fourth day I tried to stop taking medication for fever I felt better temperature 37.5 but in the evening again 38.5 drugs taken , I take the second batch of broncho vaxom 6z10 tablet , in addition, dry cough not annoying, was wet for a while coughed up thick yellow phlegm , and again dry cough rare non-annoying . if they appear wet it is rarely eg 3 coughs out of 10 coughs rarely and then I cough up white transparent phlegm if anything coughs up at all, should I use teleadvice or is it nothing serious? And continue to beat the fever and wait?
