Maybe baby? Bfp or bfn TMI

I need help. I've had light pink bleeding May 12-14. Just felt a knot in my stomach. Period was expected exactly a week later, but did not show up. My period is never late, early, or even pink. Now I am starting to have sore boob (especially on the sides), and I extremely exhausted. I've gotten many responses that this is implantation bleeding, and the pregnancy test is EXTREMELY EXTREMELY faint. Do you guys see anything and does this sound like pregnancy symptoms.
