Test accurate enough?

Hello everyone I was just updating you guys on what's going on with me. I PROTECTED anal sex in which u was the one penetrated and I received and gave UNPROTECTED oral with a guy on July. 27th  and 1 week 5 days after this experience I started experiencing these symtoms (symptoms)

Slight sore throat that lasted for 2 days
Itching l
Glands in my neck,underarm, pelvis and legs off and on started bothering me
I've been having off and on chest pain for like 3 months on the right side
Headaches off and on
Sneezing
Fatique

I was tested for STD's on Aug.24th which is 28 days after the experience . I just got my results back today and my Chlymidia, Gonnrhea, Syphillis (syphilis), and HIV all came back negative can I say these results are pretty accurate at 28 days?
What else could these symptoms be related too mono and strep test came back negative too

You DIDN'T exposed yourself to HIV, and therefore you can't have HIV.

Cheers

see your doctor about persisting symptoms as no HIV concern
