Pregnant??

For the past 3 days I’ve had nausea with and without vomiting, gagging, craving things I don’t like, tiredness, backache. Today I had cramping and sore breast but now I have this light flow but my period is schedule for tomorrow. I have had negative test and normally with my periods I have no symptoms not even break outs just Sever cramps first day my normal flow then cramp last day. I’m literally driving myself crazy trying to figure this out😩😭
