I have sex with one unknown women on 26 Feb 2018. Before sex, She gave oral sex for me without condom (blow job). But during sex I wear condom. I believe is not broken. From 26 March 2018 onwards I have joint pain and muscle aches in neck ,shoulder, leg and hand. So I took blood test on 26 March 2018, P24 antigen test is negative and hbsag is also negative and rpr test is also negative. Now I have rib pain and armpit pain and groin pain. And in my penis the parts glans normal colour. Corona and neck have pink color it's different from glans colour. So again I took blood test on 9 April 2018 ,P24 antigen is also negative. Some one suggested me to take HIV 1 dna test. So Again I took blood test on 13 April 2018, HIV 1 provera dna pcr test is also negative and Western blot test is also negative, RPR is also negative. If the dna test results is accurate. Can I believe? Still I am so worried about HIV and other STI disease. I am so anxiety. please suggest me any other blood test for me to find out my problems.
