nausea came out of no where!!!

Hi ladies
I was wondering if anyone else experienced the same as me...
I'm 8w6d and up until a couple days ago I was doing pretty good. I only had mild/ brief bouts of nausea. My biggest complaint was that I was always tired. My mom and step mom both told me if I haven't had crazy nausea and vomiting yet, that I was probably in the clear. 
Suddenly, about four days ago I have been constantly nauseous. I skip meals often because my stomach just cannot handle it. And I throw up my dinner almost every night! 
Did anyone else have the nausea and vomiting come on suddenly like this?
