should I test?

Hi all!
I ovulated on the 31st of August, had majorly sore nipples, dizziness, minor cramping. This last Tuesday I wiped and had light pink tint to CM. Wednesday was nothing. Thursday and on every time I wipe it's brown, but nothing on my liner..only when I wipe. This is not usual for AF though my projection for it to come was the 7th. I no longer have the symptoms too.  Is AF acting up, or should I entertain myself and test with tomorrow's FMU?  I'm so confused right now!!
