How To Diagnose HIV?

Question: I had virginal sex with a hiv+ lady 8am friday 19 oct, left and came back and had another same with her at 1pm same day did not ejaculate this time. I requested we test same time. i came negative and she had a clear line and a faint line. i went to my doctor who said she was positive, then said i need to get pep 3days AZT. i finished it and still told the dr i wanted the 28 day pep which i have head of, he gave me zidovuden 28days continued from the 3rd day when i finished the AZT. all this was under the 72hrs mark up. she went to lab to test and it was positive elisa test, her cd4 1580 and viral load below <40. I have been on the zidovuden for 3weeks and this is my last week. The med truly has been heavy on me, then I had itchiness no rash burning under my entire back. It seems I have a swollen neck which i went to lancet for 4th generation dou test and sensitive antigen test 19days from exposure. after i took the 4gen XXXXXXX the lab said they needed to finish with the antigen test to clear me so far. the result were negative. I am finishing the zidovuden sunday. what are odds, they say transmission from female to male is 1-1000 and also the fact that i added the pep? I have been so worried with anxiety and depression of this act, I am married with kids and this illicit behavior is putting me at risk and close to my grave, my blood pressure XXXXXXX to 160/120 am so worried. yesterday 14th Oct 3days to finish my pep just did a rapid test that both came out negative.

Thank you Dr, I just had conversion with our hiv specialist who also advised same and said the antigen test that I did is very definite that I did not contract the virus. and I should do a pcr later to put my mind at rest finally. she said antigens are used mainly for early detection from 10-22 days when the protein pops up before later stage of antibody popping up.....

I will say the dou test antigen is a good result. My doctors quote was you are definitely negative, Unquote. She was looking at the test results.
