You're talking about a DUO test, which aren't always very easy to find in the US. You don't need a DUO test anyway, as after 4 weeks, they're really pointless. DUO tests are made to be early detection tests, and anytime after 4 weeks, a standard antibody test is sufficient...as most likely, an antibody test would pick up any new infections at that point.
We go by the official guidelines, which state that a test isn't fully conclusive until 3 months post exposure, but your negative rapid test is a very good indication that you didn't get infected, along with your partner's negative result.
Ignore the urge to overtest, as that only fuels anxiety and increases your chance of getting a false positive, which as you could imagine, causes a LOT of anxiety.
Test at 3 months with a standard antibody test (rapid is fine) and then put this behind you.
