A two-bar urine pregnancy test only means that the patient is pregnant, but it does not mean that the embryo is developing normally after the pregnancy. A positive pregnancy test may be a false positive, so the patient needs to be further examined by checking the blood chorionic gonadotropin to determine if the patient is really pregnant. After pregnancy is confirmed, the patient can also determine the embryonic activity in general by dynamically observing the changes in blood HCG and progesterone levels, if the embryonic activity is very good, it usually indicates good embryonic development in early pregnancy. The blood and urine HCG tests can only determine the pregnancy and embryonic activity of the patient, but not whether the pregnancy is intrauterine or extrauterine, so the patient also needs an ultrasound to see if the pregnancy is intrauterine. If the ultrasound shows an intrauterine pregnancy with a good HCG progesterone level, this is evidence of a normal pregnancy.
