help is needed! a little TMI

so, i have been spotting for a week +1 and just stopped. it wasn't heavy, just only appeared when i would wipe, pinkish/ a hint of brown mostly pink. this happened about 6 days till i was suppose to start AF. At first i thought oh implantation because i have 0 clotting and it was mostly like a mucus pink when i wiped (tmi i know, sorry) but implantation couldn't last that long, and i haven't got a BFP just BFN's. In the 15 years of having AF, never once have i spotted until the very end. Well now, AF was due 1/14, i am two days late and no sign of AF. This whole time has been basically crampless. only had a few for a day, but it was hardly noticeable. what do you ladies think? Please let me know! Is it implantation still or what is going on? I really need advice.
