The sudden absence of vomiting in early pregnancy does not require too much tension, as vomiting is generally related to hormone secretion in the body, and is also inevitably related to the usual diet, living habits and mood. Some pregnant women have more serious vomiting in early pregnancy, but some have less vomiting, or even no vomiting at all, which are normal. If the fetus is developing abnormally, there is usually no need to be nervous about this situation and it will not affect the fetus. During pregnancy, pay attention to rest, do not overwork, relax, and eat a moderate amount of nutritious food, which will help promote the growth and development of the fetus.
