12dpo no symptoms

So I’m 12dpo, period should start Saturday. I took a test 2 days ago and got a BFN. Periods are extremely regular. I don’t have any signs she’s coming though. Normally I’m irritable, bloated, extremely tired and my hips are painful and my feet are swollen. This month? Nada. I have sore boobs. That’s all. I feel like I do a couple of days after AF is done. I even get cm down there a couple of days ahead of time, but I’m dry as heck. Should I test day of, or should I just expect my period?
