Every pregnancy would be different. Not everyone will have cravings neither appetite. But, as long as you eat healthily and nutritious food that's good. Also remember to have materna milk and have bread, biscuits, fruits, cereal if let say you dont feel like eating. You can also eat in small portion. To avoid nausea, you can eat sour plum once awhile. And yes it is totally normal for some mummies to have nausea when eating supplements.
