What is this

so my period isn't due until another 2 weeks. According to glow my fertile week started last week. & my O day was supposed to be yesterday I know for sure that there is a chance that I ovulated earlier. But last night after sex I noticed some pink/light red blood when I went to the bathroom. I didn't see anymore until this evening. This a a pict from today. I'm curious if this is implantation bleeding or not....
