Too late to be implantation?

I’m on first day of missed af. I went pee last night and notices the lightest spotting when I wiped

This morning when I went pee there was more a little little bit heavier. I I use heavy lightly... it was still very faint just more visible. Problem is, is I’m not tracking my ovulation as I’m just letting life take way, and I’m irregular so I’m really 0-none right now. Is it a possibility this is implantation or is it too late?
