Implantation bleeding? First try after BC or ever!!

UPDATE: This lasted a couple of days, but it was ultimately AF. 😞

This is my first month of not being on BC and of trying to conceive, ever. I charted BBT and took OPK that both indicated I ovulated and I am now 10 DPO. Yesterday, I experienced what I thought looked like very minor spotting and today, just had this:

Like I said, I am 10 DPO and have never done this before. Could this be implantation bleeding? I just got married two days ago and my husband and I are eager to start a family immediately, so my fingers are crossed!

Thank you!!
