where are the facts that blue dye tests are unreliable?? everytime i see someone post a clearblue with blue dye its always same answer.....test again in a few days with pink dye?? well surely these tests are tested other wise wouldn't be on sale?? Is it a common thing that they come up faint but it's really a negative??? confused!!!
