Sincere confusion

First off I have no health insurance. Three weeks ago I had a faint positive on a pink dye test. I retested two days later and it came with a faint positive again. Went to the hospital came back negative. Went home bought a new brand pink dye test came back positive clearly and just to be sure went and bought a blue dye test and it came back negetive these tests were all take with 1.5 weeks. Freaking out can't afford a medical app again. Unless super necessary. My blood type is a- what should I do?
