Implantation or period bleeding

So AF was due yesterday but never came. So I went to the bathroom this morning and when I wiped there was pink blood. Then I just went to the bathroom again and pink blood again when I wiped. I don't feel it coming out though and I put a pad on this morning and it was clean. Nothing on it. Could this be implantation bleeding or my period coming? I'm also getting light cramping. Thank you ladies!
