I'm due for AF in 4 days and just got a faint line with a blue dye. Not getting my hopes up because after almost 2 years of trying it's hard, plus we lost one early pregnancy and I know chemical pregnancy/miscarriage is always a possibility. I think I recall hearing something that blue dyes can give false positives or less reliable. Can someone confirm this? Debating on going to get another type of test or just waiting this out...
