please help

So I'm 8w4d and I have vomited only a handful of times. But have always been nautious. Today I woke up n I can't stop vomiting. I'm so hungry but I can't even hold down water. I tried to eat eggs and toast for breakfast. But didn't hold it down. Now I am sitting here feeling like I will b running to the bathroom any min and I'm so hungry. I bought saltines and ginger ale. Nothing is helping. I'm so hungry. What do I do?
