Should i test or should i not

My af is due today.. Its still a no show. I have no cramps or any pms symptoms but sore boobs. More sore than usual. My period is sometimes out of wack and i tested yesterday morning with a frer test and got a bfn. But the wait it killing me. I have several different tests to take. Maybe take a different one and see?? Or should i wait a couple more days and sace my pee sticks??
