Beautiful Ladies,
I am currently "12dpo". I put this in quotes because I am almost 9mpp and exclusively breastfeeding. I have had two periods, one in May one in July. 
I have never had implantation bleeding before and have no idea what I am experiencing. I had minimal brown spotting yesterday and today it's a little heavier. Hubby and I BD, now there are streaks of pink. 
I have never experienced this before! Start of my period maybe? Implantation bleeding?
