Spotting after AF ..... No pictures

Last night I stopped my period after a wacky not normal period one day early and basically was over yesterday but had some bleeding and cramping. It started out very light and got heavier Monday and slowed down to almost gone yesterday. Today I've gone without a pad and I've not had anything. However, tonight a few times when I wiped after just peeing I had pinkish colored blood on toilet paper. Anyone had spotting after their period? And any advice on what todo/what it could mean?
