Could I be pregnant

I have pushed back my period on glow like 3 times now and I'm had normal cramps but my period has never came. I feel sick and nauseous almost all the time. I'm eating more than normal and foods and smells that have never bothered me make me sick now or I can smell something awful but my boyfriend and friends can't and I have to pee more than I usually do and my boobs are SEVERELY sore... Any help? Should I take a test or could it just be my period???
