Implantation bleeding at 13DPO?

Ka

Hi ladies! Anyone else experience implantation bleeding at 13DPO or around then? I thought implantation happened between 6-12DPO (mostly 9-10DPO) so I’m not sure how likely it is.

AF is due around tomorrow but not getting any symptoms yet. It’s my first month off BC (which I was on for over 15 years) so not sure what to expect.

Thanks!
