Dear Doctor,

I had sex with a sex worker on 11th Nov 2016, I used the condom that was prepared by her but as I was drunk at that moment, I am not sure if it was appropriately used or not. I did a p24 combo test on the 30th day after the exposure and it turned out to be negative.
Is the test result conclusive enough? Cause after the test I had sex with girlfriend using the condom (we also did oral sex without condom) but after days she vomited. I did regret a lot and will never do the same thing again. May I know if the virus will lead to any symptoms? I am going to do the test again on the 89th day.
Thank you so much and sorry for my bad english!
