Confused!!! Please help!

Heather • Nursing student, raising two beautiful boys and have a loving hubby! I`m the queen of my own castle!
So on 9dpo I had what I think was implantation bleeding. Well it happned one time. It was more pinkish cm. Thursday nothing this afternoon I checked my cervix and did the Qtip test and I saw blood. When I just went to the bathroom I had spotting I mean very light spotting but when I looked in the toilet I saw little chunk of tisse. AF is not suppose to be here till Sunday?? Could this still be implantation bleeding??? Boobs r sore and nipples hurt! What do you ladies think????
