Hi, I am going through a very hard time in my mind whether I should wait for 84 or 90 days to be tested for hiv, hbv, gonorrhea, chlamydia, and syphilis. Does it make any difference if it 84 days or 90 days? Do I need to test again for any of these std's again if it is negative after 84 days? It was one time unprotected vaginal sex. Thanks.
