Hi
The 4th generation test is 95% accurate by 6 weeks and will give you a final result at 3 months. The test you did at 33days is a good sign as the test is 93% accurate at that stage and the sex you had was low risk for HIV passing to you.
I would not be worried about the flu like symptoms, they can be caused by many things not related to HIV. The best way to check for HIV is with a HIV test which you have done. As this has been worrying you I would suggest getting a final HIV test after 3 months not because of the risk that happened, but because I think it can help with not developing worry at a later date.
