Pregnant or what

I need help ladies.. for the last 2 days my stomach has felt empty and hungry but I've eaten, it's made me felt nauseous. My head has been hurting, I've felt dizzy and I've been having hot flashes. I took a test yesterday morning and there was a faint line but barley visible.. my period is late by a day. No signs of AF coming either.. no cramping except for about a week ago in my left overy and been having white discharge. Any thoughts?
