It is normal to have an uncomfortable stomach at 6 weeks of pregnancy but not to vomit. Not all pregnant women will have pregnancy reactions after pregnancy, and the severity of pregnancy reactions will vary from person to person. Some pregnant women will start to experience nausea, vomiting and stomach discomfort in the 6th week of pregnancy. It is recommended that pregnant women should eat less and more meals, eat light and easily digestible food, try to increase the amount of food eaten to reduce pregnancy vomiting and meet the nutrition needed for embryonic development as much as possible. In case of severe vomiting, pregnant women are advised to take vitamin B6 orally to stop vomiting, to check blood biochemistry in time, and to correct water-electrolyte disorders with timely rehydration to avoid affecting the development of the fetus and to affect their own health.
