Help! (TMI)

So I started spotting two days ago, first very light, then a Little brown-ish, later a dark red (kind of like a brick's color) With brown And today Just a liiiiiittle bit of really light pink And light brown. It's been off And on. 
Started 5 days before expected AF. No cramping And no other symptom besotes I've been really tired but I've not been getting very good sleep for a long time.
I don't want to test too early... AF due on Friday (Although for Some reason Glow is not taking into consideracion that February only has 28 days... 🤔🙄).
What do you think I should do? Test if this spotting goes away? Or wait until AF is due?
Here is a Picture of my last "wipe".
This is today's pad. I Just put one on in case AF showed Up but nothing...
