Assuming for the moment that the 0.02 is accurate, you can't know how much of a change this represents. For example, your last (or even all) past readings may have been, say, 0.019, which would be reported as <0.02. In that case the change is insignificant. On the other hand, you could have been steadily increasing from, say, 0.005.
Even with a basically stable PSA, any test can fluctuate for reasons having to do with our body's fluctuations or a test's sources of fluctuation (inherent precision of the test method, sample preparation, equipment calibration, etc.).
To give you an example, my first uPSA reading (Labcorp, after surgery) was 0.010 about 4.5 years ago and my last a few months ago was 0.018. However, my readings have gone as high as 0.034 and as low as 0.007. All were done at the same lab with the same method. (My own hunch is that the 0.034 was some one-off or error; my next-highest reading, 0.020, seems more likely as an "accurate" high. But this is just speculation on my part.)
It takes quite a few data points to determine a trend. Even if your PSA does increase a bit, it could stabilize at that slightly higher value.
