Reasons for the disappearance of symptoms in early pregnancy The disappearance of symptoms in early pregnancy means that many symptoms that occur in early pregnancy, such as nausea, vomiting, breast tenderness, etc., gradually disappear. This phenomenon often causes concern among pregnant women, because the disappearance of symptoms seems to mean that the embryo is not developing normally. But in fact, it is normal for this symptom to disappear. This is due to hormone secretion.
