10 weeks, no bloat and no bump?

Samantha
I've had severe morning sickness since week 4 or 5. I recently had to lay off prenatals for a few days because of all of the throwing up. 
I don't have a lot of bloating, and I don't have have a baby bump. Is this normal? Just kind of concerned, especially the no bloat?
I don't throw up all the time, but I have severe nausea all day.
