An ectopic pregnancy that shows positive with a pregnancy test is the same as an intrauterine pregnancy. Because there are no abnormalities in the early stages, only the fertilized egg is laid outside the uterine cavity and it will start to develop at this time, so the pregnancy test is the same. If you need to determine the possibility of ectopic pregnancy in the early stage, you need to take a blood test to check the HCG value, because the HCG value of ectopic pregnancy usually increases exponentially at a slower rate and the HCG value is lower than the normal value. Some patients with ectopic pregnancy will also have pain in the left lower abdomen or right lower abdomen and irregular vaginal bleeding, which are clinical signs for early diagnosis of ectopic pregnancy. The final diagnosis of ectopic pregnancy can only be made by ultrasound, which should be combined with ultrasound.
