I understand that implantation bleeding only occurs about 20-30% of the time so I know the chances are slim but what does this sound like to everyone else? I had my son 11 and a band weeks ago. I breastfeed and pump. My husband and I had unprotected sex on the 12th. I've been having cramping for about a week and just now when I wiped, I had light punk spotting. Does the timeline for our is it just spotting? And I haven't had a postpartum period yet.
