Should I retest?

[JamieLynx]

I took a HIV home test mid August 2018 after having unprotected sex in early June 2018. I believe I was testing at the 10-10.5 week mark. It came back negative. I haven’t had sex since that incident. Almost a whole year, but I’ve had a dry cough & sore throat for almost a week. Should I retest? Could it have been accurate by that time?? Thanks in advance.

Your results are HIGHLY unlikely to change if you take another test.  Your risk was also extremely low.  Consider:
The odds that your partner was HIV+ (in the US, considering every man, woman, and child - 0.3%, and not all of those people are of an age to be your sexual partner)
The odds that you got HIV from a brief, one-time encounter (0.08%)
The odds that your test, though 10 days early, wasn't accurate (2%)

All three of those would have to happen - as you can imagine, the odds that you are HIV+ and didn't test positive are astronomical.  

A dry cough and sore throat 10 months post-event is not a sign of HIV.  It's probably a common virus.  If I were in your shoes, I'd forget about this event and move on.

Thank so much! I appreciate it.

Same advice as before. Your symptoms can't prove anything so there is no purpose studying your body trying to work up an HIV diagnosis.
You were given testing dates before, so I am not sure why you are asking about that again.

I also asked if the test is reliable at 10.5 weeks. Thanks.
