Implantation bleeding?

Kayla • E 11/18 💙 Wife 👰🏻 TTC #2

I ovulated on Dec 26 (CD 15) with confirmation from OPKs. I’m 11 DPO (CD 26) and AF is supposed to start CD 30 and my periods are regular.

At around 11:45 am, I wiped and it was pink. It has since stopped. Could it have been implantation bleeding? I usually never start early. Pic down below of the second wipe that was a bit lighter than the first.
