Implantation or cramps?

Iyana
Ive been feeling kind of crampy for almost 3 days the last time I had sex with my bf was Friday or Saturday could it be implantation I don't have any bleeding though so I'm not sure I just want it to hurry up I've been very cranky & sleepy also I've been very hungry I don't wanna get my hopes up taking a pregnancy test tomorrow wish me luck :)
