Don't know what to do

So I've had the worst possible cramps the past two days, that they are bringing me to tears. I've been having cravings nonstop, and have been tasting things differently. My period isn't supposed to start for another week, and it hasn't started yet. I don't know if I'm about to start, because I've never gotten cramps days before my period. I'm not sure if I should go see my doctor, take a pregnancy test, or what lol. Any suggestions?
