Implantation bleeding? (Picture advisory)

This just started, early this morning it was light pink, now it's darker brown. I'm a week before my AF is due and there's just no way it's my period, I'm very very regular. This only happens when I wipe and it's not every time. I need other opinions, my fiancé just looks at me like I'm crazy, even though I am going crazy over this. Just so tired of disappointments. Help?
