Nausea, burps, bloated feeling, soft stool- are these stress related symptoms?

Stress: Yes these can be stress related symptoms but could also represent a multitude of other things. It could simply be something in your diet, a mild case of a viral illness, irritable bowel, etc. Usually i advise to wait a day or so and see how your symptoms are. Eat a bland diet and notify your doctor if you are unable to eat or drink for more than 12-24 hours.
