What is going on in this group? I've been scrolling through for the past few days and at first everyone was posting blue dye test with faint lines but everyone was telling them that it's negative or an indent and to retest with pink dye. But the problems is now is see people posting the pink frer and people are say they are known for their indents and that most the people who have a vvvfl line is negative. I'm so confused what do we test with if you say one test is wrong and we should use this instead but when we do and it has a vvfl and it was taken within the time limit that it's negative as well. I'm so confused has anyone else noticed this?
