Not sure

Not sure , may be too early for a pregnancy test but I’m starting to feel pulling pains in my lower abdomen and at times prickly . Also I’m constipated 🥴and when I eat certain things I get slightly nauseated. But , my period isn’t due for another week , should I just wait for my missed period or test again in a few days ? Oh and also I never cramp this early , and these cramps are different hard for me to explain but I know my Jody enough to know these few things aren’t normally me especially when it’s almost time for a period . Help !
