I have protected sex with prostitute. Condom was properly used. But due to fear I did provera dna test on 11th & 17th day of exposure result was not detected. But after 20 days I had swollen lymph node on both side of neck, dry cough headache & dody ache .this symptoms still persist on 31 day. I also did Hiv fourth generation test after 4 weeks. Result was non reactive. I am afraid if during kissing her body fluid (blood or saliva) may contact with my mouth. What do I do now?
