Hello and welcome to, il assist you today.
Regarding your question 4th generation test for HIV is extremely accurate and if your test is negative post 6 weeks after exposure it means your are negative as it's almost 97 to 99 % accurate.
There are extremely rare cases in which there is delayed antibody production in which its recommended to repeat a test at 12 weeks so if you have symptoms you can repeat a test at 12 weeks however please note those cases are extremely rare.
Symptoms can be due to other problems

In some people there is weak immune system so antibody production is delayed.
Immune system can be due to underlying diseases like complicated diabetes, poor nutritional status etc
