353 days hiv test conclusive?

After unsafe exposure with a csw i hv done 2.5 month hiv Dna proviral dna pcr test,4 & 5 month hiv duo eclia test,6 month hiv cmia combo test,8 month hiv elisa antibody test &hiv 1 qualitative pcr test(lower detection limit 100 copies/ml). All reports r negative. At 9 month i was facing some symptoms like rashes,headache,coughing.though rashes and headache stays for 2-3 days.but i am facing cold cough now.due to these symptoms i hv again done hiv elfa p24 antigen + antibody test on 11.5 months(353 days after exposure). Report is negative. Also tested for hbsag,vdrl,hsv1 &2,anti hcv 8 month after exposure and urine culture test for stds 9 month after exposure. All reports r negative. My question is does these test r conclusive? I am scared,depressed,anxious..
