If you keep having nausea and vomiting, it is best to first recall when your last period was. If there is a history of menopause and a history of sexual intercourse, you must first rule out the possibility of pregnancy. Because pregnancy is affected by estrogen afterwards, there will be some corresponding clinical reactions, such as getting up in the morning with nausea, dry vomiting, or having anorexia or more saliva. Therefore, it is recommended to use the morning urine to do the early pregnancy test, and if you are not pregnant, it is recommended to go to the hospital internal medicine department for an examination to exclude the symptoms of vomiting caused by gastrointestinal dysfunction.
