I'm so lost

According to flo my period should have started Tuesday. I have tested every other day since. All negative. Still no period not even a sign of my period coming, normally I get cramps, head aches, and easily irritable right before my period. But I have had none of those. I'm happy, I have been cleaning all week and it hasn't effected my mood (normally I get grumpy after cleaning all week) I have been craving mexican food and ramen both of which I normally am not a big of. I have also been crying but they aren't sad crys. I'm crying cuz my kids are adorable, my husband looks nice and treats me well. So idk. I'm hoping I get a positive but they aren't showing up and neither is my period. Also my periods are regular ish normally 28-31 days, im on day 32.
