(TMI PIC) Implantation Bleeding or Ovulation Bleeding?

Sabi • Baby girl born 12/12/12. ttc baby #2. Baby dust to everyone!
Had sex day before "AF" arrived last cycle. CD1 light spotting, CD2 medium. CD3 stopped. CD4 light then it stopped. Very Odd. CD13 light red blood streak in CM assumed ovulation. CD16 this comes for one day. When I had my first baby I never had this. Took HPT on CD16 negative. If ovulation I baby danced 2 days ago, do I still have a chance?
