BFN at 12 dpo but AF is late two days later

Alexis
I took a FRER at 12 dpo (two days ago) and af was due today. I'm getting more than usual creamy cm and getting weird symptoms. I just assumed I was out because FRER says it's 99% up to three days before expected period. Should I just wait until the weekend to test again? Usually I'd at least have spotting by now and I've never had a cycle longer than 30 days. I hate these yoyoing feelings of hope and disappointment.
