Healthy Food to ease nausea

I'm 6 weeks now and i keep feeling nauseous and my stomach bloats. While I've got medication from the doctor, i try not to take it too often. I realised i feel nauseous once my stomach feels abit empty so I'm constantly snacking esp when I'm in office! Been snacking on gummies, chocolate, biscuits. It's not exactly healthy thus i need some healthy suggestions please. Thanks! #firsttimemom #advicepls
