STOP TWEAKING and editing photos!!!!

I just say this because I was for sure I was for sure I seen lines on every test so I had a girl tweak them and they all had lines and even when u invert the color there is always a faint line!! I did this with the dollar store test and the strips ...and noticed depending on what angle you take a pic of the test the line will show up more ... Then I got my period ;( I will never tweak a picture again!
