The results of the blood test for pregnancy will be available on the same day, and the blood chorionic gonadotropin is the most reliable basis for determining whether or not you are pregnant. If the chorionic gonadotropin level is higher than normal, the pregnancy will be confirmed and an ultrasound will be performed to determine if the pregnancy is intrauterine or ectopic. In general, the vaginal ultrasound can detect the gestational sac at around five weeks of pregnancy and the fetal heart and germ at around six to seven weeks of pregnancy. If the ultrasound confirms an early intrauterine pregnancy after 50 days of pregnancy, but there is no fetal heartbeat or fetal bud, it is more likely that the embryo has stopped developing. If the increase in chorionic gonadotropin is minimal or tends to decrease and the progesterone level is low, it can be determined that the embryo has stopped developing and it is recommended to terminate the pregnancy in time. If the blood chorionic gonadotropin is normal, pregnancy can be ruled out.
