How early can you be nauseated if might pregnant?

Nausea, commonly known as morning sickness, is a common symptom of pregnancy and can begin as early as 2-3 weeks after conception. However, it's important to note that not all pregnant individuals experience nausea, and the timing and severity of symptoms can vary. The nausea associated with pregnancy is thought to be caused by the sudden rise in pregnancy hormones, specifically human chorionic gonadotropin (hCG). The exact relationship between the hormonal changes and nausea is not fully understood, but it is believed that changes in brain sensitivity and activity in areas like the hypothalamus and limbic system play a role.
