Curious about implantation bleeding

Hi, this is probably going to be a silly question to some. But I'm about a week and a half away from af showing up. Me and the dh have been ttc for a year and half now. And yesterday evening I had some pink spotting that lasted for two wipes. My af is never early but is always usually a few days late. Could this be implantation bleeding?
