Question on HIV

Hi

I think I had an exposure on February 22, 2008 which was unprotected vaginal sex with a massage parlor woman. I keep doubting that the exposure was in February because of my anxiety and I think maybe I have HIV. The tests I have had so far are:

May 16th 2008: HIV Antibody (Negative)
May 19th 2008: HIV DNA PCR and HIV Antibody (Both negative)
July 29th 2008: HIV Antibody (Negative)
October 3rd 2008: HIV DNA PCR and HIV antibody (Both Negative)

1) What are the chances I have HIV and do I need to test again?
