Insight PLEASE!!!

Thank you in advance for reading this and hopefully commenting some Insight for me.

The numbers based on what everyone else is saying doesn’t match up with what my body has felt. They say that implantation occurs 6DPO. I know I ovulated on 11/26 from my ovulation tests. And my body was having serious ovulation cramping that whole evening. But then on 4DPO I had what felt very much like implantation cramping and light brownish spotting that evening. I have continued to have light cramping on and off for the past three days. AF is due around the 9th (or 10th according to my other app).

Is it possible to implant that early? Or am I out this cycle and AF will be here early?
