Morning sickness & cravings Q?

Hi, I was wondering if it was normal at 6 weeks to actually get woken from being so sick, like I'm extraa nauseous and really sick to my stomach, but no vomiting & my craving for sugary things is super bad to the point I was eating a taco & I wanted to vomit(TMI) I even started gag and then I ended up getting nauseous once again. Am I normal or should I visit the dr?
