Nausea is one of the earliest signs of pregnancy. While breast tenderness is often the first noticeable sign of pregnancy, nausea usually starts quickly after that. Nausea can begin as early as the second week of your pregnancy. Most of the time, nausea does not start until between the fourth and sixth weeks of pregnancy. This will typically be between five and seven weeks after the end of the last menstrual period. Nausea during pregnancy typically subsides between the 12th and 14th weeks of pregnancy.
Similarly, estrogen, another hormone that increases during pregnancy, is associated with an increased frequency of nausea and vomiting during pregnancy. It's possible that nausea and vomiting during pregnancy might indicate that you're experiencing the normal climb in pregnancy hormones needed for a healthy pregnancy. However, high pregnancy hormone levels aren't consistently associated with nausea and vomiting. Keep in mind that a lack of nausea and vomiting during pregnancy isn't cause for concern. Some women with healthy pregnancies never experience morning sickness.
