So I done a test this morning at 8ish. I seen a faint line that my camera was struggling to pick up was a little more clearer than the photo below(test on the packaging). And after 20mins and I know after 10mins test have to be disregarded but the line became more darker(test on the white background). My partner then asked me to do another test at 10am but the line was alot more fainter than my first test. I'm gonna test tomorrow and then Friday to see if it's a definite but what do you guys think?
