pregnant? take a test?

So I was supposed to start my period yesterday haven’t started. I have been having random very light cramps which is very very unusual for me as I have extremely horrific cramps during my period. I have never experienced cramps befoe getting my period which makes me feel even more weird. Everything I try to eat makes me want to puke. Of course I force myself to eat as I need to eat. I pee a lot as it is but lately i wanna say for the past two weeks I PEE ALL THE DAMN TIME! every five minutes I swear. My pierod IS NEVER EVER LATE! This is the first time i haven’t been stressed, my eating hasn’t changed everything I do is what ive been doing everyday. So should I take a pregnancy test?? If so should I wait till friday or wait longer to see if it comes?
