Alright ladies, I've heard many different things....do you prefer the pink or blue dye tests, and why? 
​I normally get the blue dye test because I heard from a random woman at the store that they have "less false negatives". The Internet has articles all over the place singing praises of both blue and pink dye tests. 
​I figure this thread would give us all a little reference as to what each other prefers.
