Late. Anyone ever get a really late positive?

I like but hate that glow doesn't give any insight on why my period Is 6 days late. I like it cuz I don't want to get all excited for something that probably isn't there but I would like it to say SOMETHING! LOL I'm 6 days late, all negs, no symptoms and I had a miscarriage in September and got my period in October. I'm thinking it's just cuz of the miscarriage? Irregular period? I have read that a lot of women have experienced getting negs all the way to being 7-10 days late! Anyone?
