The gut and brain have a definite and strong connection. My oldest daughter has IBS, fueled by anxiety and my youngest has actually vomited during a panic attack.
As Hibee mentioned, if this is a new symptom for you, seeing your doctor just to rule out any physical issue is always wise...but I wouldn't be surprised if all checks out fine and this is just stress related.
Work your coping skills my friend! (and dried ginger, tea, or candy/chews can bring relief)
