First timer

This is my first time trying to conceive and i’m not sure when i should take a pregnancy test, i’m currently a day late and i’ve been having slight cramping in my lower back and lower abdomen. I have also been really tired lately, more than usual and my appetite is crazy i can be hungry all day even after i get a meal. idk i really would love to be pregnant, i’m young and if it doesn’t happen, okay but i’m really hoping. Should i test now or should i wait till i’m a week late?
