Implantation bleeding?

I had a faint line on pregnancy test on the 1st then even more fainted lines on the 2nd negative since then. My peroid is due today last night I went to wipe there was a bit of brown pink not much. Today when I go to the bathroom it's stringy with red in it. No blood in the toliet only a bit on my pad and toliet paper. Pictures attached to show what it looks like how much blood. Is it implantation bleeding or AF? I never seen it look like that before.
