Help, any input appreciated

So I'm 2 days late, which NEVER happens. I had a miscarriage Feb 2018, that is the last time I had a missed period. So of course I'm making myself crazy. No reason for it to be late, no change in weight, no stress, no change in my life.

I attached 2 photos. I have a feeling it may be a chemical. I have a test at home with a faint line. This test I feel like I see it in the black one. Anyone else or is it just wishful thinking?

I HATE my period but I hate it this more. I'd much rather it show up on time, then to give me false hope.
