What can I eat today after vomiting all day yesterday/last night?

I went to the ER last night after vomiting from 6am until 10pm (when I went to the ER). I am pregnant, and I am worried baby isn't getting enough nutrients. Is there anything today I can eat to help? So far I have been able to keep pop sickles and a single cracker down. I was given an antibiotic, fenagrin (sp?) and fluids through IV last night and a prescription for fenagrine for the constant nausea. However, I haven't gotten to take that because the pharmacy is being slow today. I am super nauseas...anything that would help?
