The false pregnancy phenomenon, which also has two bars on the test paper, is mostly related to the failure of fertilization of the egg, endocrine dysfunction or psychological stress of the woman. If there are suspected pregnancy symptoms, it is recommended to go to the hospital for detailed examination to determine. Common causes 1. Failed fertilization of fertilized egg: When using early pregnancy test paper for examination, a fertilized egg is formed and has been bedded down, but the process of bedding down is affected by harmful factors such as viral infection, drug damage or radioactive damage, resulting in the failure of fertilization of fertilized egg, which will lead to a positive early pregnancy test, but with the onset of menstruation, the performance is considered as false pregnancy; 2. Endocrine dysfunction: some women have increased levels of luteinizing hormone and lactogenic hormone due to endocrine dysfunction, which can lead to false pregnancy symptoms and the phenomenon of two bars when using early pregnancy test paper; 3. Psychological factors: women are especially eager to get pregnant or are worried about pregnancy, resulting in high psychological pressure, leading to hypothalamic function and endocrine dysfunction, which may induce pregnancy-like symptoms and cause the phenomenon of two bars on the test paper. The main symptoms of false pregnancy include nausea, vomiting, fatigue and drowsiness, and in severe cases, breast enlargement, areola deepening or swelling of the upper limbs. The most accurate way to determine if you are pregnant is to test your serum chorionic gonadotropin. If your serum chorionic gonadotropin level is elevated, you may be pregnant, and you need to use ultrasound to check for a fetal heartbeat to rule out ectopic pregnancy. If there is no menstrual flow for a week, but the serum HCGH value is normal, it is considered that there may be a menstrual disorder and pregnancy can be ruled out.
