Implantation bleeding?? 🔴🔴TMI🔴🔴

Jessica • Mommy of two. Audrey Kathleen 1.5.15 & Our Angel Baby 9.19.15. Never in my arms but forever in my heart.
Is implantation bleeding red or brown? I had some light spotting this morning that turned into a dark brown color. Had this same pad on for most of the day. Could this be implantation bleeding??Â
