Feeling defeated😢😢

I am now 12 days late.. I have had all the pregnancy symptoms, and all test have come back negative even my blood work. I really though this was it!!! And now I have a light brown discharge what is usually what I get right before I start.. and I wouldn’t see implantation bleeding this late would I? But it’s brown so that can’t be it😩 should I still be hopeful?? Or am I just wanting to see that BFP so bad that I think I’m having symptoms??
