Period two days late, negative test

My period is N E V E R late.

This cycle, my boobs haven’t hurt like they normally do- just sensitive nips the past two days, I’ve been crampy, lower back hurts, and I was nauseas off and on yesterday.

But I’ve taken a test every other day for the last 5 days, including the first day of my missed period, and they’re all negative.

I’m confused.

Any experiences like this???

Did you end up getting your period? Late BFP? What gives lol
