When I woke up to go to the bathroom, I had some pink spotting when I wiped. I checked my cervical mucus and it was pink also. Nothing more since. I'm 7 dpo and AF is due in 7 days. Do you think it's implantion bleeding??  Really hoping it is! No other symptoms except being exhausted, but not being able to sleep through the night, and REALLY vivid dreams. Breasts and nipples don't hurt, but I do feel like my nipples are hard more often than not.
