Most pregnant women start to have early pregnancy reactions around 40 days of pregnancy, i.e. 6 weeks. The occurrence of early pregnancy reactions is related to the increase of chorionic gonadotropin level in the pregnant woman’s body, and also related to the pregnant woman’s physical and mental conditions. The more common early pregnancy reactions are dizziness, fatigue, drowsiness, loss of appetite, nausea, aversion to oil, vomiting, and so on. There are also some patients who experience emotional changes during early pregnancy. For these symptoms, the main thing is to pay attention to rest and light diet, while avoiding excessive emotional fluctuations to avoid aggravation of the reaction and monitoring the growth and development of the fetus. Most pregnant women have early pregnancy reactions that will disappear naturally at about 12 weeks after menopause.
