If she had not had any unprotected sex 3 months before the test and she received a negative result and if that is the only risk you had then you didn't have a risk.
wat about a 73 day test? do i need retesting? sex with a school friend and condom broke. she had test at 7 weeks after our event and i had a test at 10 weeks 3 days.
11 weeks and 4 days in enough.
No it doesnt, its within the period, you dont need to test again, you are not going to seroconvert within a 4 day time frame. Move on with your life.
I think the actual time frame is usually given as three months, which would actually be 90 days. Your test was after 81 days. It's very likely that you're fine, and you probably don't need to test again, particularly if the "exposure" you are worried about was low-risk.
