4th Gen Test

Hi. About roughly more than 3 weeks ago I had unprotected oral and protected vaginal sex with a condom on with an HIV+ woman whom I didn't know had it at the time. I might add that I'd shaved my genitals an hour and half before sex and am afraid of abrasions or small cuts posing a significant risk if they came into contact with her saliva or vaginal fluids.

Since then, I've had an oral swab taken 15 days after exposure (too early to detect anything, I know), as well as a 4th generation antigen\antibody blood test taken at 20 days after exposure and both turned out negative.

I have had no acute HIV symptoms so far (today is the 23th day) for the entire duration - no fever or flu or sore throat or rash or swollen lymphs, and I have no other STDs - all the other STD tests turned out negative too. My doctor told me I was already at very low risk.

I have been experiencing severe anxiety for the last week, and my doctor says that symptoms I have experienced: increased salivation and wanting to spit whenever I am more stressed, tingling in my throat and feelings of it being scratchy sometimes that pass, sometimes a tightness around the chest, fitful sleep and waking up feeling tired, are all classic anxiety symptoms. I know that isolated symptoms that are temporary don't mean anything and so have been trying very hard to not stress or panic.

I have another oral swab test and another 4th gen blood test scheduled tomorrow at exactly 29 days. Is a 4th generation HIV1/2 antigen\antibody blood test taken at 20 days after exposure and showing nonreactive conclusive? Most of the reports online say the test is highly accurate after a window period of 2 weeks and above. Should I be worried?

P.S. These are the results I got:

Test Name :HIV AG/AB,4TH GEN Result: NON-REACTIVE Flag(s): Reference Range: NON-REACTIVE Reported Date: 6/7/2016 12:38 PM Footnote: U

A Nonreactive HIV Ag/Ab,4th Gen result does not exclude HIV infection since the time frame for seroconversion is variable. If acute HIV infection is suspected, HIV-1 RNA TMA Qualitative (16185) testing would be recommended. The performance of this assay has not been clinically validated in patients less than 2 years old.

Sorry, edit: today is the 28th day. No fever or any other symptoms other than woke up tired and feel a bit like my throat is a little raw (like after you've been crying).
