Pregnancy sickness is not a signal from the baby, but is caused by the increased levels of progesterone in pregnancy and the difficulty of the digestive tract in adapting to this change. Pregnancy sickness usually occurs at 6 weeks of pregnancy, is most noticeable at 8 to 10 weeks of pregnancy, and gradually disappears at 12 weeks of pregnancy. This is due to the rapid increase in hormone levels during early pregnancy, which stimulates the digestive system and can manifest itself as nausea, vomiting and other symptoms, and is not a signal from the baby. Whether the baby is healthy or not needs to be judged according to whether the blood HCG level changes normally. It is recommended that after pregnancy, a woman should monitor her body’s HCG on a regular basis to determine if it is doubling regularly. If the symptoms of pregnancy vomiting are more obvious and seriously affect daily life, it is recommended to consult a doctor in time and follow the doctor’s instructions for appropriate treatment.
