Okay freaking out here.. Light yellow CM and now brown CM just now?!

Still a week away from my period due date and I’ve never had spotting like this in my life. Is it a good sign? Or bad?

1DPO: tiny bit of yellow-tinged cm when I wiped

6DPO: same, yellow-tinged cm when I wiped

8DPO: little yellow cm @ 1 pm and just now a little brown cm @ 5 pm

Seeing the brown just now I got a huge sinking feeling like something’s going wrong 😓 Ahh, deep breaths!
