Hello However, answer is little bit in detail but it is important , so that you can in better way: Antibodies to HIV begin to appear within 2 weeks ( 14-15 days ) of infection and the time of period between initial infection and the development of detectable antibodies is rarely more than 3 months . So in your case just three days passed , so you have to wait for 11 more days for conclusive result. 2nd point is approximately 50-70 % of infected experience an acute syndrome following primary infection. Symptoms are : fever, pharyngitis , headache / retro-orbital pain, lethargy/malaise, arthralgias/myalgias, anorexia/weight loss , nausea/vomiting/diarrhea . Erythematous rashes, mucocutaneous ulceration in mouth and on tongue. I also mentioned these symptoms so you can take a concrete step and don t be in panic. Good luck.
