Pregnant or not

My period is still 2 days away and I’ve taken test after test and they’re all negative but I FEEL pregnant. I’m nauseous, my stomach has that tight feeling near my pelvic bone? If that makes sense. I’m really out of breath, exhausted, have sore boobs, my face is all of a sudden dry and my cervix is very tightly closed. I’ve been pregnant a total of 6 times so I know how it feels but I’ve never not been able to get a positive at least 5 days before my period. I’m not trying so I hope I’m not but has anyone experienced this? What was the outcome?
