Hello! I’m a FTM and I’ve been having bad nausea and some days I can’t even eat anyth w/o vomiting. What should I do?

I’ve been feeling very sick recently and can’t keep food down, can’t finish food, sometimes can’t even eat. I’m taking dilectin but the nausea and vomiting is still there. I am a teacher, so it really affects my work. What should I do? I’m at week 10. Please help!
