feeling a little sad and concerned

I don't really feel pregnant.. I did before, bloating and some cramping... sore boobs, weird cravings... peeing sooo much.. occasional nausea. Now I haven't really peed as often as I had been, I had one really big bad day of nausea where I had cold sweats and spent most of my day on the bathroom tile. I have hardly any appetite. My first ultrasound is the 11th.. I'm 6w3d. Is this normal?
