You've written here a couple of times about irrational fears and all of a sudden you have unprotected sex? Hm. Well, no. You can not attribute any symptoms to HIV 6 days after. If you 'really' had unprotected vaginal and anal with someone, then you will need to test at 28 days with a Duo, 4th generation test. But A. did this really happen? B. it was with a friend who presumably you KNOW if they are HIV + and the likely are NOT and C. a one time episode of unprotected sex is not a risk. You will have to wait until the window in which you can test and please do not think every ache, bump, cough, sore is ANYTHING to do with HIV until then because you will drive yourself crazy with that stuff. Symptoms are NOT used to diagnose HIV.
