Hi, I got drunk at a party in continental Europe in early June 2013 and had unsafe sex with an unknown partner, from which I acquired penile gonorrhea (I discovered this a few days later). 3-4 weeks later, I developed acute diarrhoea for 3 days, accompanied by mild fever and sweating, day and night. Since then (more than 3 months) I have been sweating a lot and often feeling hot/skin warm to touch, my temperature varying between about 36.5c/97.7f early morning to occasionally 37.5c/99.5f in the evening.
I have had HIV tests at the following timescales, all carried-out by the same NHS GUM clinic: 42 days after sexual encounter, 51 days, 86 days and 113 days. I have not had any sexual contact since I caught the gonorrhea.
I am confused about window periods and the accuracy of tests - there is too much conflicting information online and it is hard to know what accurate, reliable and official sources. For example, I have seen online that it sometimes takes people longer than 12 weeks or even 6 months to test positive, even using modern tests. Is this true???
Would it be true to say that, if the symptoms I mentioned above had anything to do with HIV, I would have tested positive?
Can I be assured that, with all of these negative tests carried-out in a UK hospital GUM clinic, I am definitively and conclusively HIV-negative?
Thank you for your assistance.
