Pregnant? Or all in my head?

Nicole • Hey ladies! I'm a makeup artist/special effects artist, if you need prom, wedding, play makeup I'm the girl Pm 4 app.
So I have all the symptoms, nausea, fatigue, on and off appetite, my boobs....please don't bump into me or even hug me. Cramping in my belly and I'm craving chocolate milk one second and the next I want pickles >.< I'm about two days late of my period but the pregnancy test said I'm not pregnant. Am I supposed to wait till the day after my period is supposed to end? And does the test have to be taken with the first morning pee? Maybe I should just see a doctor?
