I had sex with one of my friends who gave me chlamydia , then after a while i started to panic about my risk of contracting HIV , we had sex once in the evening and once in the morning the time i had gotten chlamydia , so i started to panic , she got tested at 4 weeks negative from her last encounter not me , and i got tested at four weeks and a couple days from the encounter i had with her and came out negative, am i at high risk? she does not use drugs , needles and neither do i. so in conclusion we both showed negative results at 4 weeks. is that accurate? im nervous and can't sleep we both had the blood ELISA test.
