Symptoms are never a good indicator for HIV infection because the symptoms can be caused by so many other problems. If you try to analyze things simply based on symptoms, you are going to freak yourself out, probably needlessly.
usually symptoms of ars is from 2- 4 weeks, but lots of people who are hiv pos dont ever have symptoms. if you have had a risk take a 3 month test and that will tell you. its flu season so alot of people are sick right now.
