Random Vomiting

I'm 26 weeks pregnant and the past two days I have been vomiting up all of my food. It's very strange because I don't feel sick at all. I'm not even nauseous at all before I get sick. My mouth waters and then bam, I get sick. Did anyone else have something similar? Any advice? 
I am making an appointment to see my OB tomorrow.
