Everything feels different

Im not pregnant well atleast the pregnancy test

says im not and af is due tomorrow. Usually with my periods I get really bad cramps. This time my cramps feel completely different I feel pinching and minor cramping. I have been nauseous and waking up between 1-2 am with nausea and crazy food cravings. My boobs feel heavy and super sore. Maybe its all in my mind but has this happened to anyone.
