Means her test will not tell you anything about your status.
the HIV negative test on the sex workers is show that 1 mth ago she do not have HIV right? if within the window period she was not infect HIV am i am in safe right?
Yes, her negative test all that means is that 3 months prior to her test she did not contract HIV. But she could have gotten HIV 2 weeks prior to your broken condom. So a 3 month test is required for you.
