tmi cm post possible implantation

Okay so i don't temp or use OPKS, I chart off my apps and my regularity and my cm. I've been super regular for over a year now,  and I don't medicate nor have any reasons of infertility. I am either 8,9, or 10 dpo and I am experiencing some pinkish cm after I went pee, only happened once. I ovulated either the 23,24 or 25. My boobs are full and sore and have been having a weird sensation when I shower. Could this be implantation ? I never spot between periods
