Morning sickness or is something wrong?

Is

Hi everyone. I am 6 weeks and 4 days today and for the last 3 days I have been consistently nauseous. It’s so bad that the thought of any food makes me sick to my stomach. I have to force myself to even eat saltines. My head is killing me on and off, but my stomach is constant. I feel like I have to throw up but nothing comes out. I start feeling sick about 10 minutes after I wake up in the morning and it lasts until I fall asleep. Is this normal morning sickness or do I need to schedule a doctors appointment? Any tips for medicine, food,

or tricks that helps?
