Test Results After Oral Sex - Should I continue to test?

Roughly 50 days ago, I gave unprotected fellatio another male. He did not ejaculate nor was there any blood. Despite this, I began to panic. I realise there is a very low risk (debatable to even theoretical risk if there was blood or "meth mouth"), but I still worried.

I believe they used 4-week DUO tests for the following:
At day 11 post exposure, I tested negative for all STIs (chlamydia, gonorrhea, syphilis) using blood/urine tests.
At day 27 post exposure, I again tested negative for all STIs (chlamydia, gonorrhea, syphilis) using blood/urine tests.

2 Weeks later (41 days post exposure) I began to come down with a flu (extremely sore throat, fatigue, runny/congested nose and coughing up phlegm, some slight headaches, though no fever). Because of this, I feared it was latent ARS so I got tested again.

This test was a POC rapid 6 week test by the same clinic. They also ran my STIs again- tested negative for all STIs (chlamydia, gonorrhea, syphilis) using blood/urine tests, as well as negative for chlamydia and gonorrhea in the throat via throat swab.

I checked with the UK hotline (Terrence Higgins Trust) and while they said this was extremely low risk and I shouldn't be as worried as I am - even noting I should not even be testing for this, they said they consider 8 weeks conclusive. The testing site I visited noted that 6 week POC test was conclusive (as is 99.89% accurate with never a sign that it changed from negative to positive).

Now I ask you - Do I still have reason to worry? Should I get an 8 week test? If so, what kind?

Thanks for your help!

You never had a risk for HIV and did not need to test, but since you did, you can trust the negative results.

You can also trust the results for the other STD's you were tested for, and you do not need to test again.

Please relax. You're clean.
