Obgyn or physician?

Hello ladies! I'm pregnant with my first and every day seems to get worse with morning sickness. I'm nauseas vomiting and faint all day long. I haven't been able to work for a week. I've tried ginger ale, saltines, even preggy pops. I'm 7w1d. I do not have my insurance yet for my pregnancy though. Which Doctor do I need to go to about getting something for this? My obgyn or just a regular physician? Please help! And if you have had another trick work to settle your morning sickness I would love to try it!
