What was your exposure and why did you take only 2 days worth of nPEP? That would do no good in a true risk situation. IN order to be effective, the entire course of nPEP must be completed.
it's a long story. would two days of pep affect the result though?
It could, in theory, but I doubt it. Testing at 2 weeks after two doses of nPEP would be entirely too soon to test anyway!
If you had a risk, test at 3 months post exposure for a conclusive result.
That's the best answer I can give you without any details. Most likely, you probably didn't even have a risk, most people that think they didn, did not.
