Morning sickness?

Hey guys I was wondering if any of you have experienced morning sickness at night? I’m 11 weeks today and I woke up around 4 to use the restroom couldn’t sleep so I felt hungry. I got something to eat and out of no where, I have to run to the bathroom to throw up. Is this normal? It’s just I’m not used to morning sickness. These past couple of weeks only thrown up 3 times lol
