Thoughts... Need some help!

ok i am expected to have AF tomorrow but no signs of it coming as of this morning.... however, about an hour ago when I went the bathroom I noticed this....

it's only a little bit when I wipe. its lile a pinkish brown...more pink then brown. Then just now I noticed this.....

It's lighter than the first one and more of a brownish tint to it. Is this the dredded AF or could this be implantation. I have never seen it like this before. Ususlly when AF shows and I start spotting, an hour later it's usually a full on period... but that's not what's happening right now it's almost fading away. Thoughts? ***UPDATE*** Ok so according to the glow app I am now late. Yesterday I had this above spotting and then I woke up to nothing.... a few minutes ago I have a very little amount of brown on the toilet paper.... like very little. Any thoughts on what this might be? I tested last nught and got another negative so I am so confused. if it were the start of my period yesterday I would have a full on cycle right now but I don't have anything!
