Am I or aren't I?

I'm so super impatient and excited to get pregnant that I can't tell if these signs I'm having are real or made up in my head. It's driving me insane!! Last month I was convinced I was pregnant. Turned out to be pms. Now this time around I'm feeling completely different and just "weird". Slightly dizzy but not really. Always super hungry but super picky about what I want to eat. I woke up in the middle of the night nauseous as heck for no reason and I'm still pretty queasy today. But the thing is, if I am pregnant, it just happened like not even a week ago so it's either all in my head or I'm just sick right?
