Is there a cure for morning sickness?

Ok...so Ive tried saltines before I get out of bed, and ginger ale, which has yet to work. Im 6 weeks pregnant and feel I got a long road of this ahead of me. Its hard for me to hold down solids right now and that worries me. I am 18 and this is my first baby. What can I do, or try, to help me with my morning sickness???
