Implantation bleeding??

We have been ttc for about two years, most consistently the last few months. We BD the 24,26,28,29, and 1st of November. My predicted ovulation was the 30th but I think it was actually the 31st. AF is supposed to make her arrival on Friday the 13th. I’ve had headaches the last three days which is abnormal for me, as well as mild nausea and fatigue. Today when I wiped it was a light pink, only enough to see on the tp. Tested this morning and it was negative. Still early, I’m aware. I just have no patience. This TWW is killin me. So, my question is could that be implantation bleeding?

I’m trying real hard not to symptom spot yall🙃
