Off and on symptoms?

Carolann

I’m very newly pregnant, only about 4.5 weeks, I’ve had some off and on cramping for the last week or so. Nothing major just a noticeable twinge. Today, I had a very water mouth almost got sick twice. In between each bout of nausea, it went completely away. Is this normal? With my first I didn’t have any symptoms so I’m new to this. Please help
