False pregnancy can occur in the case of psychological and physiological reasons. The psychological reasons are due to the desire to successfully get pregnant as soon as possible, or it may be in the fear of whether or not to get pregnant, both of which can lead to mental tension and anxiety, excessive stress, and excessive fatigue. At this time, the main manifestations that are more similar to pregnancy will appear, such as delayed menstruation, weak positive morning pregnancy test paper, and there will be nausea, vomiting, body fatigue, drowsiness and other reactions. This is actually not a real pregnancy, but a psychological disorder caused by mental stress. Physiological reasons are caused by endocrine disorders or gynecological diseases. In women with endocrine disorders there may be false pregnancy such as menopause, nausea, vomiting, etc., but the chorionic gonadotropin in the blood will not be elevated, and there will be no pregnancy. There are some gynecological diseases that can cause elevated levels of chorionic gonadotropin in the blood, such as chorionic epithelial carcinoma, which can lead to false pregnancy.
