Advanced digital test
Using the advanced digital test. I had a few leftover sticks and holder from a previous cycle, so I used those this cycle. I got a low, then two days of high. That box was empty, so I went to a new box, and got a low. Again the next day, a low. I figured I missed my peak. I tested again the next day just to see, and I got peak. How could I go from high to low to peak?
