3 days early with cheap test

Hi everyone! Last week I came down with pneumonia and have been on all sorts of meds... cough medicine, antibiotics, steroid shot... and I’m still taking them but this morning had a feeling that I should take a test knowing it’s still early and knowing these are cheapy ones. Could my meds have anything to do with giving me a false positive? Might be dumb idk but I might just be in shock too. Calling the doc when they open!
