Implantation bleeding? Advice/help

This is my current monthly chart. According to glow today is my prime day of ovulating. When I went to the bathroom this morning, there was a small amount of blood on the toilet paper when I wiped. At this point it has now turned into a brown spotting/discharge. Could it be implantation bleeding? Has this happened to anyone else? What's your advice or thoughts? 
AF isn't due until July 8th
