This is probably a false positive hsv2 test. Your index value - the numbers - dropped, and didn't go up, indicating that you most likely don't have it. Anything below a 3.5 has at least a 50% chance of being a false positive, and the lower the number, the higher the chance it's a false pos.
It takes up to 12 weeks to know for sure, though, so stop testing until 12 weeks.
It's not reacting to covid or the vaccine, but it could be reacting to the hsv1. The blood test, in theory, looks for antibodies, but what it really does it look for things that have similar molecular weights as hsv2 antibodies. Hsv1 antibodies might be included here, but normal blood proteins can also be detected.
So don't test again until 12 weeks, and then see what it says. Or you can wait until 12 weeks and get a Western Blot test. That's a far more expensive test, but it's a lot more expensive one. We can talk about that if we need to when the time comes.
So hang in there, and don't worry.
