More moody

I’ve been WAYYY more emotional than usual before my period and I’ve noticed that my boobs have gotten rounder and almost more full. I took a pregnancy test 2 days ago and it was negative. Should I test again if I don’t get my period? Everything bothers me and I’ve been having weird food cravings and I’ve been extremely nauseous in the morning but I also have secondary adrenal insufficiency which makes me nauseous as well so it’s hard to tell what is what. Could it just be my period? Or pregnancy?
