Pregnant??

Cramps, frequent bathroom trips, grumpy, depressed, always feel hungry, dizzy at times, and when I eat I feel like it's going to come back up, and at the moment I'm nauseous. 6 dpo period is due on the 17th. But I thought  your breast would ache and you would spot and feel bloated? I've felt everything except no sore breast, bloating or spotting. Heck I haven't even puked I'm just now feeling a little sick. Am I pregnant or is it something else? Help? Anyone I need ur stories or tips or something I'm excited but doubting myself at the same time! We want a baby!!
