Early AF or Implantation bleeding ***Update***

Well AF was due on the 27or28th but I believe she just showed up😞 I was having slight cramps yesterday and my boobs were sore as well as having back aches.. and yesterday would have been 6/7 DPO earlier that day I noticed brown in my CM and at the end of the night I noticed some light pink spotting this morning when I went to use the restroom I wiped and there was pink/ very light red not very dark but on the way to getting there. I don't know I don't feel like I'm on my period I'm not cramping and my boobs are still sore the soreness usually goes away by the first day it AF.. I want to believe it is IB but I think AF is here what do you think? Trying to stay positive but I got my hopes up and I think shouldn't have.
