Need advice

I’m 8w and honestly feel like I’m dying. I can’t eat anything, I throw everything up and that’s not an exaggeration. I feel so incredibly weak. I’ve also been having some cramping, no blood. I have a humatoma on the right of the baby. I just don’t know what to do. I not eating, and when I do I throw it up. I dry heave all day. My first appointment isn’t untill the 19th and it’s over the phone. I’m just at a loss. What should I do? (Have history of loss and high risk due to preclamsia with my daughter)
