PINK AFTER I URINATE BUT NOT SPOTTING

So I’m suppose to start my period tomorrow but I’m typically late or really really late so I’m not counting on starting lol. But! It’s wierd because for the last three days I have been having like a pink little spots on my toilet paper after I wipe but today it was like pink almost mucus consistency. My boyfriend and I have been TTC for a year and keep getting negatives. But I have never had this happen. Implantation? Going to start my period? PLEASE HELP!!
