Late Implantation???🚫⚠️TMI⚠️🚫

TMI⚠️ so my period is 2 days late. I went on a little hike earlier, and I started spotting really light pinkish blood. With a lot of CM. And now I’m bleeding more. Could this possibly be a late menstrual or late implantation bleeding? I’m confused at this point. My periods are always on time. This is the first time it’s been late.
