Many women do not experience pregnancy nausea until around seven weeks, but I would feel it around four weeks (dated from LMP). It's usually gone by the beginning of the second trimester.Keep protein intake up to reduce the nausea. Trade the usual high-carb breakfasts for one higher in protein. Boiled eggs are a great thing to keep in the refrigerator and grab as a quick snack.I usually craved some sort of fruit in the first trimester. Itu2019s important to consume enough protein, though. A new human is being built.Prevent an empty stomach. Keeping something in there curtails the nausea. Eat small meals frequently throughout the day. During one of my pregnancies I'd always wake up so nauseous that I had to keep crackers under my pillow so that I could eat a couple of them just so I could get up and make it to the kitchen to get breakfast. Nothing ever sounded good except watermelon that time. I should have tried some boiled eggs or high-protein yogurt after eating the fruit.
