Early pregnancy test is best performed more than one week after pregnancy. Early pregnancy test is mainly to check the human chorionic gonadotropin in the body, the hormone is mainly secreted after the fertilized egg is laid, the fertilized egg is laid around the sixth day of pregnancy, so it is recommended that the test be performed around the first week of pregnancy to be more accurate. First of all, it can be clarified by blood test, the hormone content is relatively small at the beginning, and the content in the blood increases first, and it can be detected in the urine only when the hormone in the body gradually increases, and it needs about four weeks of pregnancy before it can be obviously detected in the urine. Secondly, the early pregnancy test can be clarified by ultrasound examination, which can also clarify whether the pregnancy is normal or not, so as to avoid rupture of ectopic pregnancy leading to hemorrhage.
