need help ASAP

Kristie • expecting my miracle baby in may 😍☀️🌺🍼
I haven't eaten anything since yesterday morning because I've felt too sick.
I just threw up A LOT of yellow liquid and there was a little bit of blood with it at the end. 
is this "normal"? I'm worried and I don't have insurance yet so I can't just go to the doctor whenever I want. 
thank you
