I previously had slightly elevated testosterone, but I've not been tested in some time. If you already know you have PCOS, I think it's likely your levels are a little higher than an average female because of that AND the fact you were tested right after a HIIT session pushed it over.
If your doc says your ovaries have improved, I wouldn't take the drugs (which I am assuming is metformin?). Redo the test on a rest day, but otherwise I think you should just keep doing what you're doing.
