11 weeks and 3 days HIV test

I had a possible exposure on the 7th of January, 2007. This was an unprotected sex with a stranger in a sex club. 11 weeks and 3 days after then i have been tested for HIV and the test came back negative. Please is this definitive(I live in England and was tested by the NHS) I dont know if the test method used (ELISA) is accurate at this length of post exposure. Secondly, the i came back positive on Chlamydia and have been given a dose of treatment which doctor says would take care of it. I'm in a dilemma on how to involve my wife on this...cos she might have contracted chlamydia from me. What can I do? Obviously, learning about my cheating would really put a big strain on our relationship. I dont know how she would take it and I'm really scared. Please help me in these two areas--(1) my hiv test is it definitive? (2) how can i go about getting my wife to get tested?

Your test is definitive. The official window period is 12 weeks but you tested close to that. 4 days won't make any difference.

If you think you've given your wife Chlamydia, I would urge you to tell her. In normal situations, I'd advise not letting her know, but Chlamydia can have a negative impact on a woman's fertility. Also, it's asymptomatic in a lot of people. Of course it's up to you, but early detection means Chlamydia isn't a big deal but it can cause havoc besides.

This must be a difficult time for you and I'm sorry that you have to go through it, but for a test to be definitive, the earliest that can happen is 6 weeks
