It means you might be pregnant. I suggest you take a digital test tomorrow using first morning urine.
I posted this same question when I found out I was pregnant. Best advice I got was to go buy a digital pregnancy test and it came out positive... no questioning "pregnant or not pregnant". Also, could be so early on that the test is just barely picking up your hormones, which explains the very faint lines.
I havent heard good thing about blue dye tests, you could just try a pink dye test as well. Like above said though the digi will give you a simple answer! Good luck!
I agree with these ladies!!!! Try a digi!
