6 weeks 3 days

I'm 6 weeks and 3 days with my first, and I feel awful with nausea and fatigue. Nothing works, and now I can hardly eat or think about anything other than feeling terrible. Is this horrendous feeling supposed to increase over the next 6-8 weeks? I'm not sure how I'll survive it. Thoughts? I know everyone is different, but I'll take any insight I can.
