I had a sex with a prostitute on 1 month ago. Used protection with having sex but did two things which are killing me- 1. Oral sex (I licked the vagina) 2. Frottage (rubbed my penis over her vagina with a condom) I did the HIV test- 1. Western blot after 4 weeks of exposure (result came negative). 2. PCR test exactly after 6 weeks (result came negative) I confused with term WINDOW PERIOD of PCR DNA test? Even after 6 weeks the result of PCR test is false or what?

Western blot at 4 weeks is not conclusive. However PCR at 6 weeks or anytime after two weeks is conclusive. You are HIV negative. However you are at risk of other STDs. Take HBsAg and VDRL tests after 90 days of exposure. For any doubt, better take private consult.
