It is very easy to apply the pregnancy test, put the test paper in the morning urine of the test subject, wait for a few minutes and observe, if the test paper shows two red bars, then it proves that you are pregnant. If one of the two red bars is light in color, it is called a weak positive and needs to be repeated after a few days. If you have a history of menopause but the pregnancy test does not indicate pregnancy, don’t worry, you can go to the hospital for a blood pregnancy test. The blood pregnancy test is much more sensitive and accurate than the pregnancy test paper. Soon after the fertilized egg is laid, the radioimmunoassay can measure the HCG in the blood of the examinee is elevated, which can prove that it is pregnant. However, an ultrasound is needed to determine if the pregnancy is intrauterine, so a positive blood or urine HCG and ultrasound visualization of the embryo and primordial heart tube pulsation can then confirm a normal early pregnancy.
