HIV conclusive result or not. Anxiety?

So, i had my exposure on 14 April '18 and had my first & last test on 24 Oct '18. Test was hiv 1&2 antibodies screening test, serum and HIV 1/2 p24 combo test. It said final result : negative below antibodies. And non reactive with 0.08 under hiv1/2 p24 combo test. I took this test on 24 Oct 2018 and the result came in the evening. If i calculate the time between exposure and test.. it's 6 months 9 or 10 days. Should i consider this conclusive? Cuz everytime i think about that..it bring doubts in my mind what if it's not conclusive. Cuz i did feel fatigue the day after exposure..it could be anxiety or idk. My skin had tingling sensation on random places.. after the day of exposure for 2-3 days. But i know that hiv symptoms don't show up before 2 weeks..so what was it? I used to feel fatigue during first week..even after waking up in the morning. Was it stress anxiety?
