I caved!!

So I have 4 period tracker apps, Glow, Ovia, My Days & Fertility Friend. I've used My Days since 2011. Just found Glow about a month ago, and Ovia and Fertility Friend from Glow. My Days has my expected period day as 9/11 but all the other 3 had today 9/14, no sign of AF yet. So with all of these BFP's popping up I caved and took a pregnancy test, even though I swore to myself that I wouldn't until I was at least a week or 2 late, BFN. I'm only 8dpo right now anyway. But now I don't have a test in the house to tempt me any more. I will now wait until next Friday to even go buy a test, if AF doesn't show by then.
