6 days before... what is it

Lexi

I went to the bathroom today and when I wiped I got this. It wasn’t enough to even got in my underwear or anything. TMI but when I shoved toilet paper up there a little bit there was a little bit but after wiping like 3 times no more blood at all. I took a nap and expected to wake up on my period but there’s absolutely no blood. My periods are normally very regular. What could it be?
