Morning sickness

I'm at almost 9 weeks, yet my morning sickness gets worse and worse. I constantly want to throw up. I can't even eat, I push through the day trying to let the food digest. I constantly throw up mucus, and juice or water. When it's just mucus taste like medicine. I am waiting to go to my ob appointment in a few days for pills that will help. I try laying down when I feel horrible yet throw up laying down drinking water anything. I don't understand why I'm so sick. Maybe because it's my first pregnancy? I hate the feeling of not knowing whether I'm having stomach pains or I'm just hungry.
