I had myself convinced I wasn't pregnant the first month of trying.

As soon as I settled on that, I had this! This is 12 dpo and AF was just due in 4 days. I had light pink and light brown mucus for 24 hours when I wiped. Very small amounts each time! It has since stopped and AF was due yesterday.

Could it be implantation bleeding? I have never had spotting like this before I start my period. When AF comes, she comes in with a bang! HELP! All BFN so far, but the last of this spotting was about 36 hours ago. Please please give me your thoughts!
