HORRIBLE pregnancy symptoms

Let me start by saying I have an appointment with my doc in 2 days and will be bringing all of this up to them.

I’m almost 8 weeks pregnant, and I feel like I have had the worst pregnancy symptoms so far. I feel terrible (nauseous, so much pain in my stomach, exhausted, no appetite, headache) 24/7. I literally gag any time food is put in front of me. And then yesterday I was at a store and started getting dizzy and light headed, everything around me started to go black, I was dripping in sweat, and having trouble breathing. I had to sit down with my head in between my legs for 10 minutes before I felt better.
