Missed period

Was supposed to get my period Saturday 2/6 tested 2/7 came out negative 😩 still no period, no cramps. Watery discharge is crazy, keep thinking it's my period and it's not. On top of that I want to eat everything under the sun. I always get my period on the days I'm supposed to, my period is very regular. Im confused, do I test again ? Am I pregnant or is my period just late?? This never happened with my 2 other children. Help!!
