Implantation bleeding or AF?

A

I have tested as recent as when I woke up today and it was negative. I wiped a few times this morning and got this. I thought it was AF, but now 12 hours later she’s still not here. Is it possible it’s implantation bleeding this late? We also did BD around ovulation a couple times but I didn’t mark it down in the app. Thoughts? When should I test again?
