Weird AF… am I out?

So this morning a bit before 11 am I got what I THINK might be AF… but it’s really weird. Ever since I got my very first period it’s always just kinda started full on, never spotting at first, I’d just wake up in the morning and it would like fall out. (Sorry tmi)

Anyway, this one started with vvv light pink spotting. I though that once I got up and moving around then it would pick up, so I put a pad in just in case. Well that was now about 2 hours ago and it hasn’t increased AT ALL.

It looks like it MIGHT have increased a tiiiny bit on paper, but that could also just be because it’s more brownish than pink now and mixed with a bit more CM.

This is so not like me.. I’m 15-16 dpo, and I thought I got a very faint positive on FR early this morning so I was shocked when I started bleeding.

I know it’s too late for it to be implantation, but could I still have a chance? Could this just be delayed spotting from implantation, or something else?

If it doesn’t increase, when should I take another test?
