Vvvvfl/Tweak...

Ok. This might just be me, but seriously... if you have to tweak your "vvvvfl" test like crazy to see if there's a line, don't. Wait a couple days and re-take the test. I know waiting is easier said than done, but in my opinion that's better than using filter upon filter to see a line that may or may not be there. Don't get your hopes up, only to be let down if your picture with 10 different filters doesn't have a line after all. Or go to your doctor for a blood test.
