I see it on the green but it doesn't look darker than the other green tests. I'm sorry, I don't see anything on the One Step. I don't trust One Step 100%. I have seen so many super faint lines on mine which haven't meant anything. You have seen my One Step from today and to be honest I don't completely trust it. If you are seeing something on a One Step, or any IC which you feel could be positive, then I would back it up with a better test to be sure x x
