Extreme morning sickness?

I’ve tried everything from mint, gum, sour candy, ginger, crackers, bread, even watermelon and everything to help my morning sickness. Today I have been constantly throwing up and only managed to eat 4 crackers. Nothing is helping even water and sucking on ice is making me sick. I’m just over 6w and I desperately want the pain to go away. I’ve done nothing but be in my bed in misery for 3 days constantly throwing up and not eating. Please help me out.
