Implantation bleeding?

Okay guys I was suppose to start my period Tuesday. But instead I was spotting a pinkish tan discharge. It was very light. Then Wednesday it darkened up at bit and then Thursday it got to a brown color but it happened only when I wiped. I had some light cramps so I figured I’d start bleeding which I didn’t. The spotting that I was was extremely light and only happened when I wipe. The first picture was the first day and then the second picture is from Thursday. Can someone tell me what’s going on
