Nausea? Again?

Juanita
OK...so I am 33w and 4 days. I had nausea in my first trimester but haven't had it in months...this morning I woke up and felt fine until I got in the car and immediately felt nauseous. When I got out I threw up a couple times. I don't have fever or any other symptoms. Just nausea... Is this normal for this stage?
