Spotting, IB?

lexi

Okay ladies, I had light pink spotting on 10DPO 11DPO and 12DPO(yesterday) I took a test last night and BFN. I stopped spotting yesterday evening and haven’t started again. Could it have been 3 days of implantation bleeding? If so, when should I expect a positive. I got my BFP at 12DPO with my first and had no spotting.
