Implantation Bleeding or Period spotting???

Sorry for the below graphic but could someone tell me if this IB or just spotting? My AF is due on 17th, I'm anxious this time. We took a break from all the Clomid, Femera and <a href="https://glowing.com/glow-fertility-program">IUI</a> cycles this month and trying naturally with Vitex. Let me know your thoughts please!!
