Did you say you went on PEP at 29 days? That's obviously not how pep is prescribed so I hope I'm wrong on that. If I am wrong and you were on pep at 29 days when you tested, that would not be conclusive as hiv testing takes place AFTER pep is finished to be accurate. A test at 21 days after pep is finished is very likely to not change. But not conclusive until 28 days after. And if the other person did not have HIV, you could get it. Actually HIV is quite hard to contract and less than 1 percent transmission takes place with a single anal sex exposure.
A duo is conclusive after 4 weeks so if that is what your partner used then obviously you don't need to test. If he doesn't know what kind of test he used then he should take a duo now OR you can test for yourself after 28 days - but you don't get hiv after each encounter so your test won't prove his status.
hiv docs can't diagnose from symptoms so you should stop worrying about your throat.
