There are no tests marketed or sold to give a conclusive negative test earlier than 3 months post exposure.
I work out and everything and since I have a strong immune system,what are the odds of it going positive? :(
but they say 4th generation tests have 99% accuracy after 4 weeks :(
In this case you need to be tested 12 or 13 weeks after your exposure.
However, with your 5 weeks and 3 days negative and the fact you're circumcised, all the odds ARE IN YOUR FAVOR for your negative test at the proper time.
My risk was unprotected vaginal sex but I am also circumcised
You're not saying what was your risk.
In the USA and most countries the guidelines recommend to test 12 or 13 weeks after a known risk for a definitive result. However, anyone with a negative result at 6 weeks should be calm that he/she is not infected, as by this point almost everyone will have detectable antibodies. 5 weeks and 3 days is an excellent result, but you should do a follow up test at 12/13 weeks if you have a known exposure.
