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.
You may begin to notice more pregnancy symptoms such as morning sickness. About 50% of pregnant women will experience morning sickness. Morning sickness normally begins around the 6th week of pregnancy, but it is not too soon to begin preparing for how you will deal with it. Morning sickness can be experienced in the morning, throughout the day, or in the evening.
