If two red lines appear on the pregnancy test, it is normal that you are pregnant, but some pregnancy tests are not of good quality and may produce misdiagnosis. Therefore, it is recommended to go to the hospital as soon as possible to improve the blood HCG and ultrasound test if two red bars appear on the pregnancy test in order to accurately clarify whether you are pregnant. The blood HCG test can accurately tell whether you are pregnant or not, and by measuring whether the blood HCG is growing fast and doubling well, you can know whether the quality of the embryo is good or not. Ultrasound examination can on the one hand see the development of the embryo in the uterus, and on the other hand can exclude ectopic pregnancy. Because ectopic pregnancy is very dangerous in case of rupture, once it is diagnosed, hospitalization is recommended, and in most cases, surgery is required.
