Hello, It's Been 35 Days After I Had Unprotected Sex,

Hello, It's been 35 days after I had unprotected sex, after 2 weeks I felt I had hiv symptoms like headache and continuous stomach upset also I lost appetite to eat, the last time my partner had unprotected sex before mine was back in December, we recently went for a test and it came out negative. Please do I still have any course to be afraid?
