should I go to the hospital

I have thrown up everything I have eaten today, literally everything, I'm burning up and i havent been able to sleep. I've been up since 2.a.m. this morning until now which is 8:00pm. insomnia has hit me something hard I'm 21 weeks and baby is kicking and making it hard to get comfortable to sleep. did I throw up everything bc I'm exhausted and havent gotten enough sleep. or should I be worried. I've been dealing with morning sickness since 11 weeks.
