So I'm 14DPO and I'm not testing yet because I want to see if my period will come instead of getting my hopes up:( but 4DPO I was spotting light brown for 3 days. I had to use a pad but it was not a heavy flow,on and off..  My CM was blood tinged twice during the spotting. I've been having pregnancy symptoms but don't want to seem crazy,I know implantation bleeding usually isn't till 6DPO-12DPO but I know a couple people who bleed at 4DPO. I never spot in my life ever!
