I had sex with prostitute 16 of last month which was protected sex. while removing condom the fluid of vagina touched my cut on finger... I was very stressed and I have done few test on 20th day after sex.. The test were HIVDuo, HIV DNA,p24,HIV 1 RNA,VDRL and all the tests are negative... still I have doubt in my mind about window period.. the doctor I have consult with told me not to worry about it...
