If you do not experience nausea in pregnancy is it a bad sign?

30% of women will have no nausea during pregnancy. Not having nausea during pregnancy is relatively normal. Studies about nausea during pregnancy have not been able to conclusively determine what exactly it is about pregnancy that can cause nausea. Some researchers suggest that the rapidly changing hormone levels in your body, combined with an enhanced sense of smell and excess stomach acids are to blame for nausea during pregnancy. Another theory suggests that the buildup of a specific hormone known as hCG or Human Chorionic Gonadotropin, which builds up during early pregnancy but starts to level off after about the 12th week of pregnancy, may be responsible for nausea during pregnancy. This would seem to perhaps be the strongest theory, as nausea during pregnancy levels off for many women after their first trimester. Nausea can be 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. If you do not experience nausea during pregnancy, you are in the minority, but still within a normal percentage. Not having nausea during pregnancy should not be a major cause for concern. While some research has linked a lack of nausea to an increased rate of miscarriage, but there have been other studies that suggest the opposite. There is no conclusive research to suggest that a lack of morning sickness indicates any sort of problem with the pregnancy
