Tested for hiv after 1 month and came out negative. Still showing hiv symptoms, should I be scared?

I had unprotected sex about a month ago. Days later I had sore throat and and a rash on my wrist. Later that month I had night sweats, headaches, fever, more rashes on my hip, wrists and ankle. I am also having pretty bad joint pain. I have read that these are all symptoms of the hiv virus. I am so scared, so scared that I went and tested myself yesterday on national hiv prevention day. The test came out negative, but I still will go in three months. Is there a good chance that I have not contracted the hiv virus? I feel so depressed and scared. Please be honest with me.
