help three TMI pics. look at own risk

I need yalls help please!!!! thoughts??? I only have you girls to turn to... cycle day 19.. period due is SIX days. it's never earlier than a day and never later than a day.. or it hasn't been in the past YEAR. could this be implantation? the three times I have wiped today it has looked like this! implantation or start of period? opinions please!!

UPDATE: still no sign of anymore red at all. {that was the only red blood I saw that is in the picture} usually before my period I get really nasty brown blood. but this time is pink tinged which is what is freaking me out so much and it's so early!!
