Nausea in the first month of pregnancy is a normal early pregnancy reaction, so there is no need to be overly nervous. Due to the individual differences of pregnant women, the time of nausea and vomiting varies slightly. In the first month of pregnancy, the endocrine disorder in the body and hormonal changes are very big, so some sensitive pregnant women will have nausea and vomiting early; most pregnant women will have nausea and vomiting only in about 5-6 weeks after pregnancy, and the symptoms are mild and do not affect normal eating and can be tolerated; while some pregnant women will have late nausea and vomiting, or even will not have it. Usually, pregnancy vomiting disappears on its own in the third month of pregnancy. If nausea occurs, due to excessive secretion of stomach acid, you can eat weak alkaline food to relieve it, eat more fresh fruits and vegetables to enhance appetite, and avoid greasy, cold, spicy and stimulating food. You can walk moderately to promote gastrointestinal tract peristalsis and help digestion.
