Period or Implantation?

So I am 11 DPO. I don’t start my period until this Sunday. Yesterday I noticed I had a few drops of clear liquid coming from my boobs. Which has never happened since my last pregnancy 4 years ago. Yesterday and today very light pink/brown spotting where it doesn’t show on my liner only when I wipe. Headaches started yesterday and mild cramps nothing crazy. Excuse the picture but this is what it looks like when I wipe. Any thoughts of this is implantation or just an early period?

I’m waiting to take a test
