Wait what?

Elle! • Hello Beauties!Just waiting for our Happily Ever After to be completed with a little angel! All with do time!
I thought I was out but AF is due today and hasn't gotten here. I had a tiny bit spotting 2 days ago, so I for sure thought I was out. But it's gone. I'm 12 dpo today. Do I still have a chance?
