Possible Implantation?

Sierra

4 days till AF/11 dpo and I have very light pink spotting. Only a few drops when I wiped. Never had that happen before a period. Since 5dpo I've been cramping, on and off nausea through the day, extremely sore boobs, lower back pain. Same symptoms for ovulation, early pregnancy and early period 🤦 so idk what to think at this point? Any advise on your experiences with implantation symptoms would be appreciated!!
