How long into a pregnancy does nausea typically begin?

The onset of nausea and vomiting symptoms after pregnancy varies from person to person. However, generally speaking, about half of women begin to experience symptoms of nausea and vomiting around six weeks of pregnancy. These early pregnancy reactions usually include nausea, vomiting, dizziness, fatigue, breast tenderness, and others. Among them, vomiting is the most common symptom and typically occurs around six weeks after the last menstrual period. Some women may experience these symptoms very early in pregnancy. Especially for those who are pregnant for the first time or are younger women who are more sensitive to pregnancy, nausea and vomiting may appear as early as 20 days after conception. Conversely, women who are older or have had multiple pregnancies may experience milder reactions, and in some cases, may not experience significant nausea or vomiting throughout the entire first trimester. If you experience similar symptoms, it is recommended to seek immediate medical attention for professional diagnosis.
