I'm a bit concerned, should I test?

So lately I've been feeling kinda off. Dizzy, fatigued and having slight cramping. I wake up feeling kinda nauseous and after I eat I feel the same. For about two days I was extremely bloated in a way I haven't really experienced before. I get my period in 3 days and it seems like the closer I get to if the more off I feel. I've been extremely hungry and by that i mean i feel like i can't get full enough no matter how much I'm eating which isn't really like me. I don't know if these could be signs or I'm just paranoid.
