Could i be pregnant


The hearts are when i had sex and green are my fertile days, my period is supposedly start on the 7th of this month( its the 10th now) i still haven’t got my period but I’m not having much symptoms besides cramping on my lower back and the right side of my stomach In the front. Should i wait another week to see if i get my period or take a test. I am praying I’m pregnant 🥰 but i need some advice on what might be going on
